上假肢运动学逆解可视化研究

摘要

针对上假肢的结构特点,提出用机构运动等同性条件和代数法相结合的方法来解决上假肢运动关节变量的逆解问题,以避免多次逆矩阵相乘.利用 VB 对 CATIA 进行二次开发,在 CATIA 软件中实现上假肢关节各个解所对应的空间位置姿态图形显示,可直观地判断解的有效性,为上假肢运动控制研究奠定基础.%A method based on algebraic and identity conditions for mechanism is presented to solve artificial upper limbs inverse kinematics problems. The method can avoid multi-times inverse matrics mutiplication in the course of deduction. The spatial positions of each joint angel are shown in CATIA by secondary development of CATIA with VB. It can determine the solutions directly and lay the foundation for movement research of artificial upper limbs.
