    摘要:

    结合并联机构与串联机构的优势,设计了一种新型混联机构,该机构由3UPU并联机构和2自由度旋转机构串联而成。对该机构进行了自由度分析。分步分析其位置正解,先运用封闭解法对3UPU并联机构分析,得到3UPU并联机构的位置正解;然后采用坐标变换分析在2自由度旋转机构作用下,3UPU并联机构位置正解的变化,最终得出了该混联机构的位置正解。

    Abstract:

    Combining the advantages of parallel mechanism and serialmechanism,a new hybrid mechanism was designed.It was built in series by the 3UPU parallel mechanism and two degree of freedom (2DOF) rotating mechanism.The freedom of it was analyzed and the forwardsolutions of its position were analyzed step by step.By use of a closed solution, the 3UPU parallel mechanism was analyzed to obtain the forward position of 3UPU parallel mechanism. By use of the coordinate transformation,the change off or ward solution of position of the 3UPU parallel mechanism was analyzed under the functional role of 2DOF rotating mechanism. Final results are obtained for the hybrid mechanism of forward solution of position.
