针对伺服系统中传动系统的机电耦合影响了系统的动态特性和响应特性,提出了基于伺服系统的精密传动系统的机电耦合因素,分析了机电系统耦合建模方法。以大型精密卧式加工中心伺服进给系统为研究对象,通过分析系统各组成环节的数学模型,得到了该系统的动态结构图,建立了该系统的机电耦合模型,仿真分析了精密传动系统的传动刚度和传动误差对伺服系统的影响。利用该模型可以分析参数变化对伺服进给系统稳定性和动态特性的影响,为参数优化提供了计算模型。
Electro-mechanical coupling facts about transmission system influence dynamic characteristic and response characteristic of servo system. The coupling factors of precision transmission system are put forward, and the modelling methods of electro-mechanical system are analyzed. Based on the large-scale precise horizontal machining center, the dynamic chart of servo feed system is gained through analyzing mathematical model of the taehes, and the influence on transmission stiffness and transmission error is simulated in precision transmission system. Through changing parameters in servo feed system, the influence on dynamic characteristic and response characteristic is analyzed, so it provides a mathematical model for parameter optimization.
