摘　　要：设计了一种以伺服电缸为加载系统的角接触球轴承组件角刚度测量仪。为提高测量仪的精度,建立了伺服系统的数学模型,并提出了一种由粒子群算法整定PID参数的控制方法。仿真和试验表明:与常规PID控制相比,粒子群PID控制方法到达稳态的时间缩短了0.8 s,超调量减小了25%,而且基本无振荡现象,能满足伺服控制系统响应快,稳定性强的要求。A measuring instrument for angular stiffness of angular contact ball bearing assembly with servo electric cylinder as loading system is designed.In order to improve the accuracy of the instrument,a mathematical model of servo system is established,and a control method is proposed for adjusting PID parameters by particle swarm optimization algorithm.The simulation and test show that compared with conventional PID control,the time to reach the steady state by particle swarm PID control method is reduced by 0.8 s,the overshoot is reduced by 25%,and there is basically no oscillation phenomenon,meeting the requirements of fast response and strong stability of servo control system.
