Modeling and Analysis of Brake Judder of Middle Size Bus

중형 버스의 브레이크 저더 모델링 및 해석

In the high speed driving conditions, the vibrational phenomena with relation to chassis system are becoming more important factors in chassis design and development. In this paper Commercial Dynamic program is used to model middle size bus for brake judder phenomenon. To verify the effects of a body structure in brake judder, body structure is modeled in flexible. Also mode shapes and frequencies are obtained from Commercial FEA program in the same condition of experimental test. The simulation results are compared to the experimental results and summarized
