基于多体系统理论的机床静态精度分析方法研究

摘要

By the research of the theory of multi-body System,the principles of the modeling theory was described. Instance with a three-axis machine tool,the static precision modeling of machine tool was established. Using the basic parameters provided by the machine tool plant,the precision of level was forecasted. Comparing the predictive value and the precision of processing specimens, the accuracy of the product precision was proved.%通过对多体系统理论方法的研究,阐述了该理论的精度建模原理.以某型号三轴数控机床为例,建立机床静态精度模型,利用机床厂提供的基本参数,预测某水平面的加工精度,并将预测值与试件的加工精度要求进行对比,证明了精度预测的准确性.
