摘要

通过对新型五自由度混联机床机构（（3-RPR+R）&UPS）+P的分析，在求得该机床机构的速度雅克比矩阵的基础上，得出各分支质心速度与动平台质心广义速度的映射矩阵，并应用虚功原理建立了该新型五自由度混联机床机构的动力学模型；最后结合算例，运用Matlab和ADAMS仿真软件对机床机构的理论动力学分析进行验证，所得结果验证了理论分析的正确性及可行性。

Abstract

Based on the analysis of the new five-degree-of-freedom hybrid machine tool mechanism （（3-RPR+R） & UPS） +P， the Jacobian matrix of the velocity of the mechanism is obtained， and the mapping matrix of the centroid velocity of each branch and the generalized velocity of the centroid of the moving platform is obtained. The dynamics model of the new five-degree-of-freedom hybrid machine tool mechanism is established by applying the principle of virtual work. Finally， the theoretical dynamics analysis of machine tool mechanism is verified by using Matlab and ADAMS simulation software， and the results verify the correctness and feasibility of the theoretical analysis.
