摘要
基于集中质量法建立了由一对渐开线直齿圆柱齿轮组成的传动系统3自由度数学模型.采用一种主动控制结构,使主动控制力以更直接的方式来控制齿轮啮合点由于传动误差而引起的振动.通过压电堆作动器输出的位移控制齿轮轴的弯曲振动,以抑制齿轮传动误差,进而达到控制齿轮传动系统振动噪声的目的.在Matlab/Simulink环境中设计模糊控制器和模糊PD控制器,建立了完整的传动系统径向振动主动控制模型,并对其进行控制仿真计算.仿真结果表明:模糊控制器和模糊PD控制器均能有效抑制系统振动,模糊PD控制效果要优于单纯的模糊控制,采用的控制方法和控制策略在理论上是切实可行的.
A three freedom degrees mathematical model of a pair of involute spur gear transmission system was built using the lumped mass method. An active control structure was applied to control the gear meshing point vibration which was caused by transmission error. Through piezoelectric stack actuator displacement, the shaft＇ s vibration was controlled, which led the gear transmission error and noise being controlled. Based on the Matlab/simulink, a fuzzy PD active controller and a fuzzy active controller for system＇s vibration were designed. A complete gear transmission vibration control system was established and simulated. The simulation results show that both fuzzy controller and fuzzy PD controller can effectively suppress the system＇s vibration. Fuzzy PD controller is better than pure fuzzy controller for the gear system. The research results prove that the control method and control strategy used in this paper is practical and feasible.
