摘要
分析了影响机械结合面法向动刚度的因素 ,讨论了其特性的定量描述并提出了虚拟特性定量描述法 应用BP(BackPropagation)神经网络给出了建立机械结合面与其基本影响因素间非线性关系的方法 。
The basic factors influencing the normal dynamic stiffness of machine joints are analyzed, the quantitative description of their characteristics is discussed, and the virtual characteristics quantitative description method is put forward. Then the method for building the nonlinear relationship between the normal dynamic stiffness of mechanical joints and their basic influencing factors is given by BP network. The modeling example proves this method is feasible.
