摘要
针对某9 m公路客车外后视镜镜片碎裂问题,通过电磁振动台扫频试验及实验模态分析测试确定问题原因,最后通过改进镜体的骨架结构解决了该问题。
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.
