汽车减振器压缩行程数字仿真

汽车液力式减振器的关键参数是其阻力的响应速度。然而，传统的静态设计是确定系统过瞬态响应达到稳定状态时的参数，以夏利汽车前左减振器为模型，对其压缩行中活塞杆运动速度、阻尼力等对于时间和位函数进行了建模分析和数字仿真。为设计提供依据。为使减振器对车辆动态响应加快，选欠阻尼参数。

Digital simulation at compress stroke of hydraulic car sock absorber

The key parameter of the auto-car sock absorber is the response speed of the damping force. The traditional design way, however, cares only about the parameters at the static state. This paper took the Xiali damper as the model, set up the differential equations for velocity, damping force etc. and solved them with digital simulation so as to provide a reference for the designer to speed up the response speed of the sock damper to damping force.
