A UNIVERSAL STEERING GROMMET DESIGN APPROACH TO ENHANCE THE PASSENGER CABIN NVH PERFORMANCE

2024-26-020201/16/2024

As a car OEM, we continuously strive to set the bar for competitors with every product. Consumer travel experiences are enhanced by increasing passenger cabin silence. There is only one steering system opening in the firewall panel, which is used for allowing intermediate shaft's fitment on the pinion shaft of the steering gear. The steering grommet is the sole component that covers the firewall cut-out without disrupting steering operations, which has a substantial impact on the NVH performance of the vehicle. It is typically used in cars to eliminate engine noise and dust entering to passenger compartment. The part is assembled inside the vehicle where the steering intermediate shaft passing through BIW firewall panel. We use a bearing, plastic bush, or direct rubber interference design in the steering grommet to accommodate the rotational input the driver provides to turn the automobile. However, occasionally noise may be produced due to uneven bearing or plastic bush loading or a

Effect of Ceramifiable Silicone Rubber Composite based Thermal Insulators in Battery Packs

2024-26-035101/16/2024

Silicone and rubber composite, often called Ceramifiable Silicone Rubber (CSR) has proven to show excellent mechanical and thermal properties. CSR materials have been mainly used in industrial applications like electrical insulating cables, decorations, and fire-proof materials. The mechanical and ceramifiable properties of CSR can be altered by changing the silicone rubber matrix and by adding the right additives or fillers. In this work, we prove the potential of CSR composites as thermal insulating materials in battery packs. Specifically, we explore the usage of CSR inside the battery pack to improve safety during thermal events. We also characterize the material properties before and after exposing the CSR composite to elevated temperatures and flame. Finally, we investigate the effectiveness of the CSR composite sheet in preventing or delaying cell-to-cell thermal propagation during a thermal runaway event inside the battery pack. Our experiments show that the CSR composite sheet

Effect of environmental factors on the function of an Automotive Luggage Cover of a passenger vehicle – A case study

2024-26-022801/16/2024

Abstract: - Automobile OEMs, universally, have always given high priority to the Luggage Area of the vehicle. Luggage Area primarily includes a Load Floor (the load bearing part), Side & Rear garnishes & the Luggage Shelf (or the Parcel Tray) for covering the luggage. The Parcel Tray makes the Luggage Area look neat and aesthetically appealing & is occasionally also used for carrying small items like files, papers, cushion, tissue box etc. The article under consideration in this paper is a Luggage Cover made from thermoplastic composite such as PP-Compounds (with Glass-fiber or Wood-powder), with rotating hinges towards the cabin side. Such types of Covers are predominantly in use in many markets including India. In the vehicle, the Luggage shelf is suspended on the Side Trims or Garnishes & has an elastomer interface with the back Door. The back door tends to be opened and closed in frequent intervals and the elastomer tends to harden with time. This leads to increased load on

Road noise analysis using Component TPA and FBS with vehicle component modifications

2025-01-005505/05/2023

Road noise caused by road excitation is a critical factor for vehicle NVH (Noise, Vibration, and Harshness) performance. However, assessing the individual contribution of components, particularly bushings, to NVH performance is generally challenging, as automobiles are composed of numerous interconnected parts. This study describes the application of Component Transfer Path Analysis (CTPA) on a full vehicle to provide insights into improving NVH performance. With the aid of Virtual Point Transformation (VPT), blocked forces are determined at the wheel hubs; afterward, a TPA is carried out. As blocked forces at the wheel hub are independent of the vehicle dynamics, these forces can be used in simulations of modified vehicle components. These results allow for the estimation of vehicle road noise. To simulate changes in vehicle components, including wheel/tire and mount bushings, Frequency-Based Substructuring (FBS) is used to modify the vehicle setup in a simulation model. In this

Reducing LiDAR Cabin Noise with Damped Elastomers: a Novel Method for Predicting Performance and Durability

2025-01-011405/05/2023

Mechanical LiDAR units utilize spinning lasers to scan surrounding areas to enable limited autonomous driving. The motors within the LiDAR modules create noise that can leak into the cabin of a vehicle. Decoupling the module from the body of the vehicle with highly damped elastomers can reduce the acoustic noise in the cabin and improve the driving experience. Damped elastomers work by absorbing the vibrational energy and dispelling it as latent heat, which creates challenges in an unpredictable automotive environment. Throughout the development process with vehicle OEMs and LiDAR ODMs, highly damped elastomers were able to effectively reduce the noise created by the scanning LiDAR modules in a laboratory environment. It was unproven that these elastomers would be as effective in extreme heat, cold, or humid environments. Extensive bench and vehicle tests were conducted, but confidence was low without a model to predict behavior at edge-cases. By creating a unique test method to model

Designing Rubber Flaps for Resonance Management: High-Frequency Tuning in Electric Vehicles Using AI/ML Approaches

2025-01-012505/05/2023

High-frequency whine noise in electric vehicles (EVs) poses a significant challenge, affecting customer perception and the overall vehicle experience. One primary source of this undesirable noise is the interaction between motor pole resonance and the resonance of the engine mount rubber. This paper presents an innovative method for predicting and tuning the frequency response of engine mounts by precisely adjusting the dimensions of rubber flaps, specifically their length and width. The proposed solution employs a dual approach: fine-tuning rubber flap dimensions and utilizing machine learning (ML) techniques. An ML model, trained on historical data, predicts how varying flap dimensions impact frequency response, providing a data-driven foundation for optimization. This prediction capability is enhanced by a Python program that automates the optimization process using a linear combination formula, efficiently addressing resonance issues. By integrating ML insights with the linear

The Study of Time-frequency Domain Accelerated Editing Method for Road Load Spectrum of Automobile Rubber Isolator

2022-01-073803/29/2022

In order to improve the efficiency of durability testing of automobile parts, a time-frequency domain accelerated editing method of road load spectrum of rubber mount on powertrain was discussed. Based on Stockwell Transform (ST) theory and Accumulative Power Spectral Density (APSD), a new time-frequency domain accelerated editing method (ST-APSD) was proposed. The accumulative power spectral density was obtained by ST of the load spectrum signal of automobile powertrain rubber mounting force collected by the real vehicle in the test field. Based on this, the threshold value was set to identify and delete the small damage load fragments, and the acceleration spectrum was obtained. At the same time, the existing time-frequency domain accelerated editing methods (short-time Fourier transform and wavelet transform) were used to accelerate the editing of the force load spectrum, and the editing effects of the three time-frequency domain editing methods were compared and analyzed from four

A fatigue life prediction method of rubber material for Automobile vibration isolator under road load spectrum

2022-01-029103/29/2022

Automobile rubber isolator was subjected to random load cycle for a long time in the service process, and its main rubber material for vibration isolation was prone to fatigue failure. Since the traditional Miner damage theory overlooked the load randomness, it had a prediction error problem. In order to improve the prediction accuracy of rubber fatigue life, the traditional Miner damage theory was modified by random uncertainty theory to predict the rubber fatigue life under random load. Firstly, the rubber dumbbell-shaped test column, which was vulcanized from rubber materials commonly used in vibration isolators, was taken as the research object. The uniaxial fatigue test of rubber under different strain amplitudes and strain mean values was carried out. Then the fatigue characteristic curve of rubber with equivalent strain amplitude as the damage parameter was established. Secondly, the load spectrum of the rubber mount of an automobile powertrain was collected from different road

FEA based methodology to optimize sealing performance in Fuel vapor emission valves

2021-26-020309/22/2021

As per current global trends, low tailpipe and evaporative pollutant emissions is major focus area in automotive development. This has led to imposing stringent emission limits on both tailpipe and evaporative emission norms. In field of evaporative emissions, the fuel valves must meet zero-leak of fuel to canister requirement under different operating conditions. Corresponding sealing design iterations and evaluating the performance thru lab testing is time and cost consuming. Present study considers FEA based sealing analysis considering elastomeric-plastic interface using ANSYS. The designs are evaluated by comparing surface contact of seal with valve orifice. In present study, different combinations of shape, size of plastic and elastomeric parts, material stiffness, axis position of elastomeric & plastic parts and use of supporting structure for elastomeric parts are evaluated. A methodology is provided to optimize seal design to meet zero-leak of fuel requirement by using right

Experimental Study of Tread Rubber Compound Effects on Tire Performance on Ice

06/16/2020

Mechanical and thermal properties of the rubber compounds of a tire play an important role in the overall performance of the tire when it is in contact with the terrain. Although there are many studies conducted on the properties of the rubber compounds of the tire to improve some of the tire characteristics, such as the wear of the tread, there are a limited number of studies that focused on the performance of the tire when it is in contact with ice. This study is a part of a more comprehensive project looking into the tire-ice performance and modeling. In this study, to understand the effect of different rubber compounds on the tire performance, three identical tires from the same company have been chosen. The tires’ only difference is the material properties of the rubber. Two approaches have been implemented in this study.

Rubber material model development for closure bumpstop

2020-01-107304/14/2020

Abstract: In vehicle development process, closures slam durability is one of the important measurement for BIW & closure design. In Closure slam simulation event, the majority of dynamic forces absorbed through rubber seals and rubber bump-stops which are typically mounted in-between the closure system and BIW. These auxiliary components also provide the cushioning to the structure and protect it from the panel interaction during abusive closure slam. In conventional CAE Simulation process, the stiffness of rubber bumpstop oftenly represented with linear stiffness data which does not capture rubber behavior during loading and unloading for both static and dynamic event. Thus, it provides an opportunity to develop the numerical material model for better rubber behavior simulation.

Options for Reducing Friction When Using Silicone Elastomers

TBMG-3576901/01/2020

Silicone has a long and proven history of use with medical devices and can provide many benefits, from flexibility to cushioning. When working with some medical devices, however, silicones can present challenges due to an inherent surface tack. The surface of cured silicone elastomers is sometimes characterized by a high coefficient of friction (CoF), some degree of tackiness, and a tendency for blocking (sticking to itself by virtue of chemical affinity). These characteristics may need to be addressed in applications that require a molded or extruded silicone component to move or slide with minimal friction. Blocking is particularly evident in slit valves, for example, where the two sides of the silicone part touch each other and “heal,” or close the slit.
