摘要
传动链振动会使终端工作部件运动不平稳，定位精度差，降低机器工作精度．本文对传动链振动进行了实测，分析出振源，采用新的同频谱建模思想建立了相应的非线性振动方程，并设计了一种非线性积分控制器作为主动消振控制器．仿真结果表明，该消振控制器效果令人满意．
The transmission chain vibration will introduce unstable motion of end workparts, decreasepositional precision and working precision. In this peper, the vibration is measuted and the vibrationsource is analled. A nonlinear vibration equation is established by a new method of the same-spectral modelling, and a nonlinear nitegrator controller had been designed as an active controller for antivibration. The simulation results show that the effects of the controller are sqtisfactory.
