摘要
对一类5—5台体型并联机器人机构的结构特征进行了深入分析,提出了其位置正解分析与求解的简单方法。首先利用序单开链的思想对该机构进行拓扑特征分析和结构分解,将其运动学方程维数降至最小,然后利用一维搜索法得到全部实数解,最后将该方法应用于具体实例,结果不仅表明了该方法的有效性,而且首次给出了具有20组实数解的机构实例。
A simple method for forward displacement analysis of a kind of 5 - 5 in-parallel robot is presented, after its structural characteristic has been disclosed. First of all, the parallel robot was decomposed into three single-opened chains (SOCs). Secondly, the dimension of its kinematic equations was reduced to the minimum by considering kinematic model of the three single-opened chains. Then, all the real solutions to the kinematic equations were obtained using one-dimension searching algorithm. At last, a numerical example with 20 real solutions was given for the first time and provided to confirm the efficiency of the solution procedure.
