THE ESTABLISHMENT OF THE DYNAMIC EQUATIONS ON CAM FOLLOWER SYSTEMS WITH NON-LINEAR PARAMETER

在高速凸轮机构中 ,凸轮———从动件系统可以简化为质量———弹簧力学模型。由机械振动理论 ,建立了含有非线性参数的凸轮———从动件系统单自由度和多自由度动力学方程 ,为计算机数值计算研究凸轮从动件系统的动态响应提供了理论基础。最后 ,给出了建立含有非线性参数的两自由度模型动力学方程的实例验证。

In high-speed cam mechanisms, cam follower system can be expressed in mass-spring mechanic models. This paper has built single degree-of-freedom system and degree-of-freedom system dynamic equations on cam follower system with non-linear parameter according to the machine vibration theory. They offer a theory foundation for researching dynamic response of cam follower system by using computer numerical value. Finally, an example that set up two-freedom mechanic model dynamic equation with non-linear parameter is presented.
