Investigation of fatigue life and active vibration control via piezoelectric elements in vehicle suspension.

ABSTRACT: As the automotive industry advances toward electrification, intelligence, and high performance, vehicle operating intensity continues to rise, placing greater demands on structural components. The fatigue behavior of the suspension lower control arm plays a critical role in ensuring vehicle handling stability and safety, necessitating thorough analysis and optimization. In this study, a rigid-flexible coupled dynamic model of an independent suspension system is developed, incorporating a finite element-based flexible representation of the lower control arm and a multi-body dynamic model of the suspension assembly. Fatigue life prediction is subsequently conducted, followed by an investigation into the primary influencing factors. Furthermore, piezoelectric ceramic-based active control stra
