摘　　要：以锻造机械手典型机械运动水平直线运动为例,建立该运动过程的动态数学模型,通过变参数仿真研究各种参数对系统动态特性的影响,分析系统响应特性对控制系统及控制精度的影响。采用AT89C51单片机对步进电机进行控制,通过I／O口输出的脉冲信号作为步进电机的控制信号,对于提高大型复杂机械系统的控制精度具有参考价值。A forging mechanical hand of typical mechanical motion is taken such as aclinic motion as an example, and the dynamic mathematic model of motion process is built, researching of the effect of dynamic characteristic via changing parameters emulation, and analyzing the effect of systemic responding characteristic to control system and control accuracy . Adopting AT89C51 SCM to control stepping motor, its manipulative signal is pulse signal via I/ O output. It has referenced value for improving control accuracy of the heavy complicated mechanical system.
