在拖拉机上直接测取轮胎和液压系统刚度阻尼参数的方法

The Method of Finding the Stiffness and Damping Parameters of the Tractor's Tyre and Hydraulic Unit

本文探讨了直接在拖拉机上测量轮胎及液压系统刚度、阻尼的方法．并给出了东方红－４０拖拉机后轮纵向、前、后轮横向及液压系统的刚度、阻尼值，研究了轮胎参数与轮胎气压的关系，由此法确定的参数用于拖拉机犁耕机组模拟计算取得了满意的结果。

This peper introduces the method which can be used for finding the stiffness and damping perameters of the wheel and hydraulic unit in tractor directly, and shows the Dongfanghong 40 trac tor's wheel parameters in horizontal place and hydyaulic unit, also study the ralationship between the wheel parameters and pneumatic pressure. The parameters detemined with this method have been used satisfactorily to simulate tractor-plough unit.
