摘要
为了解决复杂铸件的打磨、抛光仍需依靠人工完成的问题,提出了一种新型6自由度对称并联机构3-PUPU机构。运用螺旋理论对该机构进行自由度的分析与计算,并应用多自由度并联机构输入选取理论选取主动输入副。然后利用Solid Works软件建立三维实体模型,并将模型导入到ADAMS软件进行自由度的分析验证。虚拟样机验证结果与理论分析结果一致。
A novel 6-DOF symmetrical parallel mechanism, 3-PUPU mechanism, is developed for solving the problem that complex castings have to be polished by artificial means. The screw theory is used to analyze and calculate the degrees of freedom of this mechanism, and the theory for selecting input of multi-DOF parallel mechanism is utilized to select the active motion pair imposed driving force. A three dimensional body model was built through the Solid Works software, and the model was imported into the ADAMS software to analyses the mechanism＇s degrees of freedom. The results of virtual prototype verification are consistent with the theoretical analysis.
