摘要
为模拟汽车减振器的阻尼特性,根据流体力学理论和减振器的实际工作原理,分别建立了车用普通双筒液压减振器的复原行程和压缩行程数学模型,以某型号汽车减振器的结构性能参数为例进行了软件仿真,并通过减振器振动台架性能试验进行了验证。鉴于普通双筒液压减振器阻尼力模型的综合性和复杂性,采用ANSYS软件Design Exploration模块,利用响应面法得到减振器各参数的灵敏度,为普通双筒式液压减振器的设计提供了有效依据。
In order to simulate damping characteristics of shock absorber, according to the theory of fluid mechanics and the actual working principle of shock absorber, the mathematical model of the recovery stroke and the compression stroke of the common vehicular dual cylinder hydraulic shock absorber was established, it took the structural performance parameters of a certain type of vehicular shock absorber as an example to make software simulation of the mathematical model, which was verified through performance test on the vibration stand. At the same time, because of the comprehensiveness and complexity of the shock absorber damping force model of common vehicular dual cylinder hydraulic shock absorber, we used the Design Exploration module in ANSYS, and the response surface method to obtain the sensitivity of each parameter of absorber, which provided an effective basis for the design of common dual cylinder hydraulic absorber.
