ZHANG Zhongdong, WANG Ke,IIU Ximming
Abstract: In view of the fragmentation problem of rearview mirror of a 9 meter coach, the cause of the problem is determined through the frequency sweep test with the electromagnetic vibration bench and the experimental mode analysis test. Finally, the problem is solved by improving the skeleton structure of the mirror body.
