复合式镗铣加工中心铣削部分空间误差建模研究

摘要

基于多体系统运动理论，结合复合式镗铣加工中心铣削部分的结构布局，阐述了多体系统的拓扑结构、低序体阵列和相邻体间特征矩阵的创建方法，分析基于多体运动学原理的复合式镗铣加工中心铣削部分空间误差模型的建立。%Based on the basic principles of multi-body system kinematics,the milling structural of the composite boring and mill-ing machine center,it was described the topological structures of multi-body system,the low order body array and the creation method of characteristic matrixes between adjacent bodies. It was also analyzed how to build the volumetric error model of the milling part of the composite boring and milling machine center.
