机械法向接触特性参数的实验方法

Testing method on normal contact parameters of unit joints

针对实验的方法获取机械结合面法向接触特性参数,首先将结合面间的接触状态等效成刚度和阻尼,建立了结合面法向接触的动力学数学模型,以该动力学模型为依据设计了实验试件结构和传感器安装结构。其次设计了实验数据采集与处理系统,获取机械结合面法向接触实验参数。

In order to obtain mechanical joint surface normal contact characteristic parameters using testing method, first, joint surface contact state simplified into an equivalent stiffness and damping, establish contact the dynamic mathematical models. In term with the dynamics model, the experimental specimens structure and sensor installation structure are designed. Second, the testing data collecting and processing system is designed. The joint surface testing parameters are obtained.
