Certainty Research of the Motion of Under-actuated Mechanisms with Flexible Joints

  • 摘要: 欠驱动机构运动学和动力学约束不完整,机构运动具有不确定性,欠驱动机构引入柔性运动副后可利用其弹性反力一定程度上弥补动力学约束的不完整,但其运动的确定性仍与机构的初始状态和柔性运动副刚度有关。针对该问题,以含有柔性移动副的平面二自由度欠驱动机构为研究对象,提出一种运动学、动力学求解的数值迭代算法,力求通过求得运动和动力约束方程的确定解来研究该类机构的运动确定性。首先,建立机构的运动学、动力学模型,然后,利用MATLAB对该机构进行求解,得出了不同初始状态下机构能够实现确定运动的最佳刚度范围,最后,通过多组数据分析得出了最优驱动力矩与柔性移动副刚度之间的拟合曲线。
