机构间隙转动副冲击碰撞模型中的混沌现象

Chaotic Phenomenon in the Impact-free Model of Mechanism Clearance Revolution Joints

以钢球与钢套组成的系统为例，对系统的碰撞特性进行了研究，建立了钢球在钢套中运动的数学模型，编制了计算程序．研究结果表明，在一定条件下该系统对初值极其敏感，表明系统的确存在混沌运动．

The system composed of a steel ball and a socket is taken for example to study the impact properties so that the mathematics model of describing the movement of ball in socket is set up and the calculation is computer-programmed. The research shows that on a certain condition, the system is very sensitive to initial value, confirming the existence of chaos in the system.
