| Abstract: | The modes need to be considered in the design process of cross car beam(CCB).It should be considered to avoid the natural frequency of the engine idling condition to solve the problem of steering wheel jitter in idling condition.Based on CAE modal analysis of CCB,the vertical bracket of CCB was modified,and the fixed points in the up and down directions with the BIW were strengthened.It can improve the mode of CCB assy effectively. |
