摘　　要：以固体火箭发动机复杂药柱整形为背景,提出了一种具有三个平动自由度的PUU并联机床。首先求解并联机床的运动学逆解方程,通过考虑其结构约束条件,以工作空间最大化作为设计目标,然后采用Monte Carlo方法对该并联机床的工作空间进行了优化分析,最后根据优化结果及机床的设计目标对工作空间进行算例分析,并利用Matlab软件仿真得到并联机床工作空间的实体模型,为该机床合理设计提供了理论基础。A three translational degrees of freedom（DOF） PUU parallel machine tool is presented as the back- ground of the complex grain machining of the solid rocket engine. Firstly, solving the kinematical inverse equa- tion of parallel machine tool, considering the constraints of its structure in order to maximize the workspace, then proceeding optimization analysis of the workspace of the parallel machine tool by the usage of Monte Carlo method. Lastly, analysing the workspace according to the results of the optimization and the object of the machine tool, utilizing M atlab software simulating the real solid model of the parallel machine tool work- space, as the base of the rational design of machine tool.
