| 摘 要： | 工作空间是机床操作器的工作区域,它是衡量并联机床性能及加工能力的重要指标,是机床工作能力的直接反映.本文研究了一种基于3-PRS-PP并联机床工作空间,通过考虑其结构约束条件,采用极坐标搜索法确定了并联机构的工作空间边界点,并在此基础上绘出了工作空间边界曲面的图形,得到了机床工作空间的三维仿真模型,并分析了机床结构参数对工作空间的影响.

| Abstract: | Workspace is work area of machine manjpulstion, is an important performance evaluation index of parallel kinematic machines. is direct reflection of work capacity. This paper presents the workspace research of a 3-PRS-PP based parallel kinematic machine. By considering the structural constraints and simulation, the workspace boundary points of parallel machine tool are obtained by a polar coordinates searching method. Based on it, the projection of the workspace boundary surfaces can be produced. the solid model of the workspace is described and the effect of design parameters on the workspace is studied. |
