为研究并联机械腿运动性能指标和结构参数之间的关系,以PRP,A,S/2-PUPR并联机构为研究对象。根据步行机器人的工作任务确定机械腿的自由度,通过求解位置正逆解证明机械腿具有部分解耦性能,并通过蒙特卡洛法搜索出机械腿的工作空间。基于1阶影响系数矩阵和2阶影响系数矩阵得出机械腿的速度全域性能指标和加速度全域性能指标,并将结构参数数值化,得出较优的结构参数范围。最后,通过细化后的结构参数的性能指标,得出最优的机械腿结构参数。结果表明,性能指标可以对机械腿的结构参数进行精确优化。
In order to study the relationship between the performance index and structural parameters of parallel mechanical legs,the PRP,A,S/2-PUPR parallel mechanism is studied. According to the working task of the walking robot,the degree of freedom of the mechanical leg is determined. The positive and negative solutions of the position are used to prove that the mechanical leg has partial decoupling performance; the working space of the mechanical leg is searched by Monte Carlo method. Based on the first-order influence coefficient matrix and the second-order influence coefficient matrix,the speed global performance index and the acceleration global performance index of the mechanical leg are obtained,and the structural parameters are numerically determined to obtain a better range of structural parameters. Finally,the optimized mechanical leg structure parameters are obtained through the refined performance parameters of the structural parameters. The results show that the performance index can accurately optimize the structural parameters of the mechanical leg.
