Totem-Pole PFC and LLC resonant converter based 6.6kW On-Board Charger for LEV Applications2026-26-01601/16/2026
As light electric vehicles (LEVs) gain popularity, the development of efficient and compact on-board chargers (OBCs) has become a critical area of focus in power electronics. Conventional AC-DC topologies often face challenges, including high inrush currents during startup, which can stress components and affect system reliability. Furthermore, DC-DC converters often have a limited soft-switching range under light load conditions, leading to increased switching losses and reduced efficiency. This paper proposes a novel 6.6 kW on-board charger architecture comprising a bridgeless totem-pole power factor correction (PFC) stage and an isolated LLC resonant DC-DC converter. The main contribution lies in the specific focus on enhancing startup behavior and switching performance. In PFC converters, limiting inrush current during startup is crucial, especially with fast-switching wide-bandgap devices like SiC or GaN. Conventional soft-start techniques fall short in of ensuring smooth voltage

Enhanced SAE 3 link Leaf Spring Model to Generate Durability Virtual Loads2022-01-03403/29/2022
Heavy-duty truck vehicles are generally equipped with leaf spring suspensions. Conventionally, beam elements are used in multibody software to build the leaf spring model to calculate virtual loads. Beam elements require a high computation time due to their numerous degrees of freedoms and force components introduced by beam connections, interleaf contacts, friction, etc. Again, in these simulations, solvers frequently fail in durability loads analysis due to sudden spike in accelerations, high suspension articulation coming from severe road profiles. These drawbacks lead to the use of simplified three-link mechanism models to simulate the leaf spring’s behavior, which is computationally faster. However, the current approach is less accurate as compared to the beam element model because this model has only a torsional spring which accounts for vehicle bounce condition. In reality, the leaf spring suspension system is also subjected to cornering and braking while running on road

On-Road Emissions of Euro 6d-TEMP Vehicles: Consequences of the Entry into Force of the RDE Regulation in Europe2020-01-22199/15/2020
Human health and the environment are heavily impacted by air pollution. Air quality standards for Nitrogen dioxide (NO2) and particulate matter (PM) are commonly exceeded in Europe, particularly in urban areas with high density of traffic. Road transport contributed to 39% of NOx emissions, and 11% of PM emissions in the European Union (EU) in 2017. Measurements with Portable Emissions Measurement Systems (PEMS) showed that most Euro 5 and Euro 6b diesel vehicles emitted significantly more NOx on the road than their permissible limit in the laboratory type-approval test. In that context, EU Real Driving Emissions (EU-RDE) regulation aims at securing low on-road emissions of light duty vehicles under normal conditions of use. This paper assesses the tailpipe emissions performance of Euro 6d-TEMP gasoline and diesel passenger cars, type-approved after the entry into force of the RDE regulation in September 2017.

A Blockchain-Backed Database for Qualified Parts2019-01-13433/19/2019
Certain standard parts in the aerospace industry require qualification as a prerequisite to manufacturing, signifying that the manufacturer’s capacity to produce parts consistent with the performance specifications has been audited by a neutral third-party auditor, key customer, and/or group of customers. In at least some cases, a certifying authority provides manufacturers with certificates of qualification which they can then present to prospective customers, and/or lists qualified suppliers in a Qualified Parts List or Qualified Supplier List available from that qualification authority. If this list is in an infrequently updated and/or inconsistently styled format as might be found in a print or PDF document, potential customers wishing to integrate qualification information into their supplier tracking systems must use a potentially error-prone manual process that could lead to later reliance on out-of-date or even forged data.

Tolerance Management in a Semi-Automated and Collaborative Human-Robot Aircraft Riveting Process2019-01-13733/19/2019
Large aircraft sizes with high precision requirements combined with complex joining tasks are typical challenges for aircraft production. To increase competitiveness and effectiveness, the automation of such production processes seems a viable solution for companies in the aircraft sector. When implementing automation, in order to handle small batch sizes and high variation while adhering to tight tolerances, the production equipment must meet high quality standards and flexibility requirements. To achieve the objectives above, tolerance management is essential: deviations are acceptable within limits, as long as they do not result in quality losses and expensive rework. For these reasons, all the interactions between the product, production process and production equipment used must be analyzed in detail. The importance of this analysis is evident in assembly where new technologies are used, such as (semi-)automation using Human-Robot-Collaboration. Despite its innovative value, this

Collaboration in a Hybrid Team of Human and Robot for Improving Working Conditions in an Aircraft Riveting Process2019-01-13723/19/2019
Aircraft production is facing various technical challenges, such as large product dimensions, complex joining processes, and organization of assembly tasks. Overcoming such challenges, as well as maintaining low tolerances and small batch sizes, is often difficult to achieve whilst retaining economic viability. ZeMA believes that a semi-automated approach is the most effective way to optimize aircraft section assembly. This can be achieved with a semi-automated riveting process for solid rivets, using Human-Robot-Collaboration in combination with an intuitive Human-Machine-Interaction operating concept. In the assembly of aircraft structures - in this scenario the aircraft aft section - the pressure bulk head is mounted to the section barrel. Two operators work collaboratively in uncomfortable, non-ergonomic positions, yet of course have to maintain exacting quality standards.

Seven Steps to Successful Contract Manufacturing for the Medical IndustryTBMG-3306710/1/2018
Contract manufacturing, or outsourcing, has typically been associated with a company using an offshore manufacturer and lower labor rates to produce their products at a lower cost than would be possible domestically. However, contract manufacturing also provides opportunities for companies looking to utilize the knowledge and experience of existing manufacturers, both domestic and foreign. This option allows companies to avoid large capital expenditures on machinery to build product, as well as the operating cost associated with running this machinery. While this can be an attractive option for companies operating in a wide array of industries, the medical equipment and device segment is one where substantial benefits can be realized.
Optical Interconnect Design Challenges in SpaceTBMG-329069/1/2018
More and more aerospace applications are incorporating fiber optics technology into their designs due to its many advantages over copper. The thinner fiber solutions provide higher speed over a longer distance, are more reliable, offer higher noise immunity and, in many cases, lower the cost of ownership. Additionally, for the same diameter, fiber can pack more data than copper. Fiber is faster than the category 5 and 6 copper cables, approaching the speed of light (31% lower). For copper, pushing the speed beyond 1G is a challenge, but for fiber 10G is quite common. Copper is limited by distance. Usually, signal degradation with copper will occur after about 90 meters (2.7 km maximum for custom systems), while fiber can achieve more than 1.5 km without a problem and can deliver over 80 km depending on transmission signal quality.

Cold Start HD FTP Test Results on Multi-Cylinder Opposed-Piston Engine Demonstrating Rapid Exhaust Enthalpy Rise to Achieve Ultra Low NOx2018-01-13784/3/2018
The 2010 emission standards for heavy-duty diesel engines in the U.S. have established a limit for oxides of nitrogen (NOx) emissions of 0.20 g/bhp-hr., a 90% reduction from the previous emission standards. However, it has been projected that even when the entire on-road fleet of heavy-duty vehicles operating in California is compliant with the 2010 emission standards, the upcoming National Ambient Air Quality Standards (NAAQS) requirement for ambient particulate matter and ozone will not be achieved in California without further significant reductions in NOx emissions from the heavy-duty vehicle fleet. Given this, there is potential of further reduction in NOx emissions limit standards for heavy duty engines in the US. Recently there have been extensive studies and publications focusing on ultra-low NOx after treatment technologies that help achieve up to 0.02g/bhp-hr. at tailpipe [1]. To achieve ultra-low NOx emission levels over the composite HD FTP cycle, rapid heat energy must be

Ford sets tech-paper record as SAE boosts quality standard17AUTP04_124/1/2017
SAE International and its industry partners are continually improving the quality and topicality of technical papers published annually. And as the paper review process has become more rigorous, the industry has responded with an increased number of manuscripts submitted over the last five years. That has helped SAE deliver maximum value to its members and WCX attendees. OEMs are helping to raise technical paper quality overall by learning from each other. The ‘Written Only’ paper category was established to give authors the opportunity to submit a manuscript at any time. With this, SAE did not need to be reliant on event ‘call for papers’ (CFPs) for manuscripts. And rather than simply rejecting a paper, organizers can now suggest that authors withdraw their paper, continue to work on it, then submit it to the Written Only portal for publication consideration. This has raised the bar on paper quality and has boosted quantity as well.

Optimizing the Rear Fascia Cutline Based On Investigating Deviation Sources of the Body Panel Fit and Finish2017-01-16003/28/2017
A vehicle’s exterior fit and finish, in general, is the first system to attract customers. Automotive exterior engineers were motivated in the past few years to increase their focus on how to optimize the vehicle’s exterior panels split lines quality and how to minimize variation in fit and finish addressing customer and market required quality standards. The design engineering’s focus is to control the deviation from nominal build objective and minimize it. The fitting process follows an optimization model with the exterior panel’s location and orientation factors as independent variables. This research focuses on addressing the source of variation “contributed factors” that will impact the quality of the fit and finish. These critical factors could be resulted from the design process, product process, or an assembly process. An empirical analysis will be used to minimize the fit and finish deviation. Experimental approach as well as Response Surface Methodology “RSM” will be used for

Testing of Adhesive Bonds on Large Industrial Components made of CFRP with a Robot Inspection System Using Active Thermography, Leading to Reduced Cycle Times2016-01-21239/27/2016
The integration of omega stringers to panels made of carbon fiber reinforced plastic (CFRP) by adhesive bonding, which is achieved by baking in an autoclave, must be subject to high quality standards. Failures such as porosity, voids or inclusion must be detected safely to guaranty the functionality of the component. Therefore, an inspection system is required to verify these bonds and detect different kinds of defects. In this contribution, the advantages of a robotic inspection system, which will be achieved through continuous testing, will be introduced. The testing method is the active thermography. The active thermography has major advantages compared with other non-destructive testing methods. Compared to testing with ultrasonic there is no coupling medium necessary, thus testing will be significantly enhanced.
