摘要 考虑抓取机械手工作于狭小圆形管道内与工作对象的分布特点两方面因素,管内异物抓取机械手采用三自由度关节型机械手的机构型式。以机械手的工作空间主截面最大与杆件长度尺寸之和最小为优化目标,建立了综合优化目标函数,得到机械手的结构参数优化解,为机械手的结构设计及运动学与动力学分析提供了基础参数。同时对所得优化结果做了进一步分析,为机械手的机构参数的修改与调整提供了可靠的理论依据。 By taking two factors that the grasping manipulator works in narrow and small round pipeline and the characteristics that the working object is distributed,the nubby object grasping manipulator in pipe adopts 3-DOF joint type manipulator as the mechanism mode.Taking maximizing main section of grasping manipulator's workspace and minimizing the sum of rod piece lengths as the optimization goal,a synthesis optimization objective function was established.Then,the optimized solution of mechanism param-eters for manipulator was obtained,providing basic parameters for structure design and analysis of the kinematics and dynamics.Fur-ther analysis on the obtained optimal result was also carried out,providing reliable theoretical basis for modifying and adjusting mechanism parameters of manipulator.
