Development of the Mild Hybrid System for Off-Road Machinery

2024-32-006704/18/2025

In recent years, the importance of achieving carbon neutrality has been highlighted in response to the escalating severity of climate change. In the leading automobile market, the share of electric vehicles is gradually expanding, especially in passenger car sector. However, it is not same in commercial vehicle sector. In the off-road machinery market, as with electrification in commercial vehicles, the factors such as the need to install charging infrastructure and the requirement for large batteries to expand operating duration are significant challenge to full electrification. As one of the realistic solutions toward carbon neutrality for off-road machines, methods to utilize both internal combustion engines (ICE) and their applied products are being reconsidered. Under the circumstances, we have developed a mild-hybrid (MH) system for small off-road machinery. This system adopts a 48V power supply in order to minimize size of the system offers as a “Drop-in” package solution. This

Perspectives and limitations of a fully electric 48 Volts propulsion architecture

2022-01-080103/29/2022

In the context of CO2 emissions reduction, investigations are currently made in various directions among the automotive sector: internal combustion en gine efficiency improvement, downsizing, electrification, vehicle weight reduction. Meanwhile, a new type of ve hicle is emerging in the automotive sector. This study analyses the perspectives and limitations of a low volt age electric vehicle (<60V), with only two people ca pacity. One of the main challenges of this new type of vehicle is to identify the bestsuited powertrain ar chitecture, given the different constraints and needs (power, mass, acceleration, range, etc.). With the ad vantage of reducing the safety constraints linked to high voltage applications, but with the expense of higher currents when power level increases, a proper power train components sizing is mandatory, therefore limit ing the advantages of such architecture. To better eval uate the evolution of the powertrain parameters, a sim ulation tool has been built to

Material Brings Optical Communication onto Silicon Chips

TBMG-3249808/01/2018

An increase in computing performance has been achieved by squeezing ever more transistors into a tighter space on microchips. This downsizing has also meant packing the wiring within microprocessors ever more tightly together, leading to effects such as signal leakage between components, which can slow down communication between different parts of the chip. This delay, known as the “interconnect bottleneck,” is becoming an increasing problem in high-speed computing systems.

Passenger Car Handling Characteristics Associated with Space-Saver Spare Tires

2018-01-502707/12/2018

Space-saver spare tires have become near-standard equipment in passenger cars, replacing full-size spares. The properties of space-saver spare tires (cornering stiffness, self-aligning torque, etc.) exhibit some differences when compared to standard size tires. We examine potential handling changes when a space-saver tire is installed on the vehicle by examining steady-state behavior, initial step steering response, and vehicle understeer gradient as functions of the mounting location of the space-saver tire (front or rear axle). Results show that space-saver spare tires perform well and are quite capable in low-ay, linear handling maneuvers.

Peelable Heat Shrinkable Tubing Enables Next-Gen Miniaturization

TBMG-2911306/01/2018

When it comes to the cardiovascular procedures, small is indeed beautiful. With the need for minimally invasive procedures and increasing moves to deliver therapies to hard-to-reach areas such as the brain, miniaturization is a niche that demands significant focus. Procedures are rapidly changing, creating a need for new technologies that can help address unmet needs. Nevertheless, as with all medical devices, the proof is in the application, and this requires supporting evidence pointing to successful outcomes.

Miniature “Pop-Up” Robot Combines Micrometer Precision and High Speed

TBMG-2881604/01/2018

Because of their high precision and speed, Delta robots are deployed in many industrial processes, including pick-and-place assemblies, machining, and welding. Delta robots use three individually controlled and lightweight arms that guide a platform to move fast and accurately in three directions. The platform is either used as a stage — similar to those used in flight simulators — or coupled to a manipulating device that can, for example, grasp, move, and release objects in prescribed patterns. Over time, roboticists have designed smaller and smaller Delta robots for tasks in limited workspaces, yet shrinking them further to the millimeter scale with conventional manufacturing techniques and components has proven fruitless.

Design Optimization of Vehicle Body NVH Performance Based on Dynamic Response Analysis

2017-01-044003/28/2017

Noise-vibration-harshness (NVH) design optimization problems have become major concerns in the vehicle product development process. The Body-in-White (BIW) plays an important role in determining the dynamic characteristics of vehicle system during the concept design phase. Finite Element (FE) models are commonly used for vehicle design. However, even though the speed of computers has been increased a lot, the simulation of FE models is still too time-consuming due to the increase in model complexity. For complex systems, like vehicle body structures, the numerous design variables and constraints make the FE simulations based optimization design inefficient. This calls for the development of a systematic and efficient approach that can effectively perform optimization to further improve the NVH performance, while satisfying the stringent design constraints. In the present work, an efficient method to optimize the structural dynamic response is proposed considering the low-frequency NVH

MULTI-MATERIAL BODY SOLUTIONS: Possibilities and manufacturing challenges

16AUTP06_0406/01/2016

The body-in-white is a prime target for lightweighting and many automakers are pursuing unique and effective multi-material approaches, but improved design tools and processes may yield greater gains. In the automotive industry, mass reduction and lightweight design is a continuing trend that does not show signs of declining. When examing where to reduce weight in a vehicle, the body is a preferential sub-system due to its large contribution to overall mass and the stability of body composition over a specific model range. The automotive industry is moving toward a greater differentiation in materials, as can be seen in the different multi-material vehicle bodies recently introduced. But while mixing materials may contribute to a good compromise between weight reduction and vehicle cost, it also proposes a number of challenges.

An Outlook on Multi Material Body Solutions in the Automotive Industry - Possibilities and Manufacturing Challenges

2016-01-133204/05/2016

In the automotive industry, mass reduction and lightweight design is a continuing trend that does not show signs of declining. When looking at where to reduce weight in a vehicle, the body is a preferential subsystem due to its large contribution to overall mass and the stability of body composition over a specific model range. The automotive industry of today moves toward a greater differentiation in materials that compose a car, which can be seen in the several different multi material vehicle bodies that have been introduced by manufacturers in recent years. But while mixing materials may contribute to a good compromise between weight reduction and vehicle cost, it also proposes a number of challenges that need to be addressed. Among other material factors, the different coefficients of thermal expansions might introduce new stresses during painting and curing. Joining processes and possible chemical reactions between materials also needs to be taken into account, the same with the

Development of Backlash-Less Reduction Structure Capable of Suppressing Wiper Reversing Sound

2013-01-095804/08/2013

A wiper system is characterized by its continuous reversing movement. This means that a wiper motor is repeatedly subjected to forward and reverse loads under the influence of the variable load which a wiper blade receives when moving on the glass surface, and of the weight of a wiper arm and blade. Consequently, the system generates reversing sound inside the motor, i.e., collision sound between gears resulting from backlash. This is a challenge to be overcome. In this study, the authors have established a new backlash-less and high-efficiency reduction gear structure by adopting pinion gears that can move in response to the load variations at reversing in the existing double worm gear reducer. With this structure, the growing needs for noise reduction, downsizing and weight saving of wiper motors can be met concurrently.

Archway for Radiation and Micrometeorite Occurrence Resistance

TBMG-1526212/01/2012

The environmental conditions of the Moon require mitigation if a long-term human presence is to be achieved for extended periods of time. Radiation, micrometeoroid impacts, high-velocity debris, and thermal cycling represent threats to crew, equipment, and facilities. For decades, local regolith has been suggested as a candidate material to use in the construction of protective barriers. A thickness of roughly 3 m is sufficient protection from both direct and secondary radiation from cosmic rays and solar protons; this thickness is sufficient to reduce radiation exposure even during solar flares. NASA has previously identified a need for innovations that will support lunar habitats using lightweight structures because the reduction of structural mass translates directly into additional up and down mass capability that would facilitate additional logistics capacity and increased science return for all mission phases. The development of non-pressurized primary structures that have

Materials lead the way to vehicle mass reduction

12MOMD1031_0311/01/2012

Reducing a vehicle's mass opens the door for a downsized engine and transmission, a lighter cradle and body structure, smaller wheels and brakes, as well as a weight-slimmed suspension. The start point for this ripple effect is materials. THE LIGHTWEIGHT MATERIALS MENU FEATURES METALS AND NON-METALS, yet the selection process is not a one-size-fits-all solution. Without question, every lightweight material choice matters, especially with the industry working in overdrive to meet the U.S. federal mandate for a 54.5-mpg fleet average in the 2025MY. That's in addition to a bevy of other upcoming governmental fuel economy and CO2 emissions regulations around the globe. Jeffrey Moyer, Vice President of Business Development & Engineering at Meridian Lightweight Technologies, said the reality is that only two critical model-year life cycles remain for automakers to reach the 54.5-mpg requirement.

Heavy on the lightweighting

12AEID1002_0510/02/2012

Weight reduction is already a significant consideration in companies' product development efforts, and the emphasis is only going to increase in the years ahead, according to SAE-member survey respondents. The U.S. government finalized in late August a regulation establishing 54.5 mpg as the average fuel economy required of cars and light trucks in MY2025. The newest set of CAFE (corporate average fuel economy) regulations begins with MY2017 products; a prior set of regulations covers MY2012 through 2016, the final year of which the CAFE requirement is 35.5 mpg. To make the almost 20-mpg leap in less than a decade-and to meet similar upcoming mandates in other regions of the world-automakers and their suppliers must develop and deploy a variety of fuel-saving technologies.

Finding innovative ways to reduce vehicle weight while maintaining vehicle safety will be key to achieving the 2025 fuel-economy target. On the road to the 2025 Corporate Average Fuel Economy (CAFE) target of 54.5 mpg, reducing vehicle mass is universally recognized as a key technology necessary to help achieve this ambitious mark. Mass reduction has been ongoing since the automobile was invented, with steadily increasing amounts of aluminum, plastics/composites, and high-strength steels in vehicles; however, the new CAFE regulations will require further acceleration in the rate of implementation, while not making any sacrifices when it comes to vehicle safety. “There's no doubt in my mind that [NHTSA'S] position is that it will accept zero compromise in terms of safety as you make these cars more fuel-efficient. And if lightweighting is one of your solutions, it will not accept any compromise in vehicle safety in terms of its crashworthiness,” said Dr. Jay Baron, President of the

Compact Receiver Front Ends for Submillimeter-Wave Applications

TBMG-1405707/01/2012

The current generation of submillimeter- wave instruments is relatively massand power-hungry. The receiver front ends (RFEs) of a submillimeter instrument form the heart of the instrument, and any mass reduction achieved in this subsystem is propagated through the instrument. In the current implementation, the RFE consists of different blocks for the mixer and LO circuits. The motivation for this work is to reduce the mass of the RFE by integrating the mixer and LO circuits in one waveguide block.

Method to Remove Particulate Matter From Dusty Gases at Low Pressures

TBMG-1407507/01/2012

Future human exploration of Mars will rely on local Martian resources to reduce the mass, cost, and risk of space exploration launched from Earth. NASA’s In Situ Resource Utilization (ISRU) Project seeks to produce mission consumables from local Martian resources, such as atmospheric gas. The Martian atmosphere, however, contains dust particles in the 2-to-10 -micrometer range. These dust particles must be removed before the Martian atmospheric gas can be processed. The low pressure of the Martian atmosphere, at 5 to 10 mbars, prevents the development of large voltages required for a standard electrostatic precipitator. If the voltage is increased too much, the corona transitions into a glow/streamer discharge unsuitable for the operation of a precipitator. If the voltage is not large enough, the dust particles are not sufficiently charged and the field is not strong enough to drive the particles to the collector.

Ring Pack for Downsized Spark Ignition Engines

2011-36-015710/04/2011

Downsized engines are considered one major technical trend to attend the demands for CO₂ and fuel consumption reduction. Usually this engine configuration consists of displacements between 0.9L and 1.2L with 3 or 4 cylinders, usually associated with turbo charge. The increased load due to high gas pressures and power density may affect the PCU components, specially the piston rings. This work reviews the ring pack used on the current downsized engines from European and NAFTA OEMs. The different ring designs and materials used on downsized engines are discussed. The specific challenges that those engines present to piston rings and the available alternatives are discussed. An extreme low friction, under development, ring pack was tested in a 1.2L Turbo downsized engine.

High Power Density Motor for Racing Use

2011-39-722105/17/2011

This paper presents the development of a motor that was supposed to be adopted in the Kinetic Energy Recovery System for the Formula One world championship 2009 series. KERS can recover and utilize braking energy in the form of power assist, with maximum energy use per lap of 400 kJ and maximum power of 60 kW. This hybrid system is expected to provide benefits such as lap time reduction and straightaway speed gain for overtaking. The motor is required to achieve downsizing, light weight, high power density, wide power band, and high efficiency. This paper describes how the on-board layout, size, and specifications were decided and how the newly developed technologies were applied and test result to confirm enhanced performance.

Vehicle Development Insights from Industry: Technologies and Trends for Future Growth - If we build it, they will come. One of the more serious legacies of the recent economic downturn is the loss of engineering talent and experience the downsized industry has endured. The experience never can be replaced, but the talent can-IF the industry does what is necessary to attract the best and brightest to our ranks. The hard truth is that the fluid power industry has a perception problem. Today's young engineers tend to see fluid power as an unexciting, archaic technology with little room for innovation or people who like to think outside the box.
