Abstract

The transition from traditional combustion engines to electric vehicles introduces a distinct challenge for car manufacturers: the emergence of higher-frequency noise generated by electric motors, gearboxes, and associated components. While conventional methods effectively dampen noise, vibrations, and harshness up to approximately 300 Hz, electric vehicles operate at frequencies ten times higher. To address this issue, a potential solution lies in the adoption of plastic materials over metal. Fiber-reinforced plastics, which are recognized for their strength and stiffness due to the high glass contents, offer promising alternatives. However, the mechanical performance of these materials is intricately tied to fiber orientation within the components, presenting a significant challenge, especially in durability assessment. 

This paper explores various methodologies for conducting fatigue strength assessments, illustrated through the evaluation of a newly developed material and test platform by Ascend Performance Materials. Glass filled Vydyne AVS material portfolio which is specifically designed to mitigate noise, vibration, and harshness, while ensuring the requisite stiffness for electric vehicle structures serves as a compelling case study in this context.
