摘要
汽车行驶过程中,外后视镜抖动是一个常见的问题.文章针对外后视镜抖动问题进行分析,找出四个主要原因:振动频率与后视镜固有频率设计不达标、后视镜内部零件配合不完善、后视镜内部零件强度不足以及后视镜安装固定不牢固.在此基础上,提出六个解决措施:优化后视镜设计、加强外后视镜内部零件配合、提高后视镜强度、加强后视镜安装固定、优化车身结构减少振动传递、采用阻尼材料等.这些措施可以有效减少外后视镜抖动,提高行车安全性和舒适性.
Abstract
When the car is driving,shaking of the external rearview mirror is a common problem.In this paper,four main reasons are found out:the design of vibration frequency and natural frequency of the rearview mirror is not up to standard,the internal parts of the rearview mirror are not perfect,the internal parts of the rearview mirror are not strong enough and the rearview mirror is not firmly installed and fixed.On this basis,six solutions are proposed:optimizing the design of the rearview mirror,strengthening the coordination of the internal parts of the external rearview mirror,improving the strength of the rearview mirror,strengthening the installation and fixing of the rearview mirror,optimizing the body structure to reduce the vibration transmission,using damping materials,etc.These measures can effectively reduce the rear view mirror jitter,improve driving safety and comfort.
