摘要

为探究电磁参数和机械参数变化对伺服驱动系统动态特性的影响,基于机械动力学和电磁学相关理论,建立一种包括电机电磁刚度和电磁阻尼的四惯量机电耦合模型;采用变步长4～5阶Runge-Kutta法对模型进行数值求解,得到系统的时间历程曲线、相平面图、庞加莱映射和幅频特性曲线;分析电磁刚度、激励频率和传动综合误差等参数的变化对机电耦合系统运动状态的影响。系统在不同电磁刚度取值下会导致系统经倍周期分岔转变为周期1运动,而后转变为混沌运动;当电磁刚度由5×10~5N·m/rad减小至10~5N·m/rad时,系统的最大幅值增大了7%;齿轮啮合误差等机械参数取值变化会使得系统运动状态发生变化,综合传动误差波动系数由0.05增大至0.2时,系统的最大幅值增大了16%。

Abstract

In order to explore the influence of the changes of electromagnetic parameters and mechanical parameters on the dynamic characteristics of servo drive system,based on the relevant theories of mechanical dynamics and electromagnetism,builded a four-inertia electromechanical coupling model including motor electromagnetic stiffness and electromagnetic damping.Obtained the time history curve,phase plane diagram,Poincare mapping and amplitude-frequency characteristic curve of the system by using 4～5 order Runge-Kutta method with variable step size. Analyzed effects of the changes of electromagnetic stiffness,excitation frequency and transmission comprehensive error on the motion state of the electromechanical coupling system.Under different electromagnetic stiffness values,the system will change from period doubling bifurcation to period 1 motion,and then to chaotic motion,and when the electromagnetic stiffness decreases from 5 × 10~5 Nm/rad to 10~5 Nm/rad,the maximum amplitude of the system will increase by 7%. The change of mechanical parameters such as gear meshing error will change the motion state of the system,and when the fluctuation coefficient of comprehensive transmission error increases from 0. 05 to 0. 2,the amplitude of the system will increase by 16%.
