【Abstract】 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.更多还原
