Fatigue Life Prediction of Vehicle Rubber Elastic Support Components Based on Physics
Introduction Rubber elastic support components are vital in automotive vibration isolation, absorbing road irregularities and reducing transmitted forces to the chassis and occupants. These non-metallic materials exhibit complex behavior under long-term cyclic loading, where temperature, frequency, and load amplitude influence fatigue life. A physics-based fatigue life prediction framework offers a systematic way to quantify reliability,…

Fatigue Life Prediction of Vehicle Rubber Elastic Supports: A Physics-Based Approach
Introduction Rubber components play a pivotal role in automotive vibration isolation, absorbing shocks and dampening noise while maintaining ride comfort. Among these, rubber elastic supports (often called mountings or bushings) are exposed to prolonged cyclic loading, temperature variation, and environmental aging. Predicting their fatigue life is essential for reliability, maintenance planning, and safety. A physics-based…
