橡胶衬套静刚度有限元分析与测试技术的应用现状

当前我国国民经济飞速发展,随着人们对于出行要求的不断提高,汽车的数量也在快速增加。橡胶衬套广泛应用于汽车悬架,其能够很好的起到减震的作用,也能够大大提高汽车悬架的使用寿命。作为汽车悬架的重要部件,橡胶衬套的静刚度很大程度上会影响汽车的NVH性能,刚度越小减震效果越好,但容易引起共振带来抖动,反之,静刚度过大不利于隔离震动,因而对于橡胶衬套静刚度的测试分析十分有必要。合适的静刚度能够最大限度地提高车辆行驶的舒适性,也能够在一定程度上保证行车安全。以下就橡胶衬套静刚度的有限元分析与测试技术进行简要的分析研究。

Finite element analysis of static stiffness of rubber bushing and the application status of test technology

At present,my country's national economy is developing rapidly.With the continuous improvement of people's requirements for travel,the number of cars is also increasing rapidly.Rubber bushings are widely used in automobile suspensions,which can effectively reduce shocks and greatly increase the service life of automobile suspensions.As an important part of the automobile suspension,the static stiffness of the rubber bushing will greatly affect the NVH performance of the automobile.The smaller the stiffness,the better the shock absorption effect,but it is easy to cause vibration.On the contrary,too large static stiffness is not conducive to isolating vibration.Therefore,it is necessary to test and analyze the static stiffness of rubber bushings.Appropriate static stiffness can maximize the comfort of vehicle driving,and can also ensure driving safety to a certain extent.The following is a brief analysis and research on the finite element analysis and testing technology of the static stiffness of the rubber bushing.
