| 摘 要： | 为了研究减振器中油温对减振性能的影响,通过对汽车筒式减振器模型进行了分析,建立了减振器阻尼与温度变化之间的关系。并以某二自由度汽车振动系统为例,用MATLAB软件进行编程仿真,初步研究了温度变化对汽车减振器性能的影响。

| Abstract: | In order to study the influence of oil temperature on the performance of an absorber,the relationship between the dampling of the absorber and the variation of the temperature is established by the analysis of a model of the absorber.Taking a vehicle vibrating system with two degrees of freedom as an example,we tentatively studied the influence of the temperature on the performance of the absorber by using MATLAB simulation software package. |
