| 摘 要： | 基于逆向思维提出了一种满足工作空间要求的五轴并联机床的尺度综合方法．首先用极坐标来描述并联机床的姿态空间；然后基于工作空间的要求得到运动平台上铰链点与固定平台上铰链点的距离极值表达式；最后考虑到杆件的力传递性能，得到一组性能较优的参数．该方法对类似的并联机构的尺度综合具有较高的参考价值．

| Abstract: | Based on the inverse thought, an approach is presented for the dimension synthesis of a 5-axis parallel machine tool to satisfy the requirements of workspace. Firstly, the orientation workspace of the parallel machine tool is described with the pelar coordinate. Then, the extreme value expressions of distance between the joints on the moving platform and the joints on the fixed platform are obtained based on the requirement of workspace. Finally, the dimensional parameters of the parallel machine tool with better performance are obtained considering the strut force transmission performance. This approach provides a high reference value for dimension synthesis of the other parallel kinematic mechanism similar to it. |
