Finite Element Model of Multi-Body Brake Quarter Car for Braking Analysis

[摘要] A finite element multi-body model was developed for evaluating the dynamic characteristics of the brake quarter car. All parts of the brake quarter car were modeled as a finite element considering the elastic deformation. Each part was connected by a joint and has a degree of freedom by kinematic constraint. After stabilization by preload, friction braking analysis was performed. The vertical acceleration of the lower control arm was confirmed. Vibration effects due to deformation of the flexible body motion not occurring in the rigid body motion were confirmed at the acceleration level. The coupled thermo-mechanical analysis considering the frictional heat generation was performed using the result of dynamic displacement assuming small deformation in the elastic region. The temperature results of the brake disc were confirmed.
