凸轮传动机构的振动分析

Vibration analysis of the cam mechanism

凸轮机构是常用的传动控制机构,这里建立了凸轮传动机构的振动模型,分析了从动件的运动规律,分析表明由于从动件具有弹性元件的特性,因而运动过程中会产生振动,从而导致其实际运动位置与给定位置发生偏差。在凸轮机构的设计和应用中必须重视这一问题。

Cam mechanism is one of the important control mechanisms.In this paper th e vibration model for the cam mechanism is established,and the motion of the output element is analyzed.The output element is of elasticity,so vibration can be ca used in the motion.In this case the deviation between the desired value and the actual value of the motion of outp ut element cannot be avoided.The pro blem is important for the design and application of the cam mechanism.
