Abstract

本发明涉及一种可动部件动作设计方法,包括:将可动部件分解为刚体和至少一个执行件,提取出需要与可动部件建立关系的目标件的初始特征参数;构建包含可动部件与目标件的几何模型;确定基本约束条件和目标约束条件,使几何模型处于全约束状态;调整目标件的特征参数,利用几何模型的尺寸驱动特性,使执行件的动作参数自动更新,记录目标件特征参数与执行件动作参数的对应关系;获得多组对应关系数据并进行拟合,建立目标件特征参数与执行件动作参数之间的映射关系,作为可动部件的动作设计依据。本发明将逆向运动学问题转化为正向尺寸驱动问题,降低了可动部件动作设计难度;拟合得到的映射关系具有极高的精度,为精确控制提供了可靠依据。
