摘要
针对在三平动3-(2SPS)并联机构一条支链上附加冗余滑动,产生运动学反解多解性的问题,开展运动分析,研究运动控制的轨迹规划准则。以避开奇异位形为准则,实施轨迹规划并进行仿真。结果表明,附加冗余驱动可使机构工作空间成倍放大,且动平台能成功避开奇异位形。
Because of the additional redundant sliding to 3-(2SPS) parallel machine,multiple solutions of inverse kinematic are found.It establishes the solution of kinematic equations of the machine,and studies norms of trajectory planning.Based on the norm of avoiding singularity,the simulations of trajectory planning are done.The result shows that redundant actuation can help parallel manipulator enlarge effective workspace,and eliminate the singular configurations.
