【摘要】：为了利于计算机自动综合,提出了改进的Assur杆组邻接矩阵的平面运动链类型自动综合。首先针对构件数主动件数和选定的杆组,根据杆组组成理论求出对角线元素以及它们的不同组合,然后归纳了综合方法和步骤,定义了选定杆组邻接矩阵。因为综合法在综合构件的过程中根据杆件数、主动件数及杆组类型这些因素分类细化了运动链,并同时判断同构构型,所以综合过程具有很强的规律性,效率也很高,可以减少后面运动链同构识别与刚性子链识别的计算量,特别是对于计算机自动综合多杆多主动件的平面机构运动链,并成功应用在综合12杆以下的平面机构运动链类型。并且以6构件单主动件机构运动链为例进行了类型综合。
[Abstract]:In order to facilitate computer automatic synthesis, an improved Assur bar group adjacent matrix is proposed for automatic synthesis of planar kinematic chain types. The diagonal elements and their different combinations are calculated according to the theory of the composition of the bar group according to the active number of components and the selected bar group. Then the synthesis method and steps are summarized and the adjacency matrix of the selected bar group is defined. Because the synthetic method classifies the motion chain according to the number of members, the number of active parts and the type of rod group, and judges the isomorphic configuration at the same time, the synthesis process has strong regularity and high efficiency. It can reduce the computation of isomorphism recognition and rigid subchain recognition, especially for computer automatic synthesis of planar kinematic chain with multi-bar and multi-active parts, and is successfully applied to synthesizing the kinematic chain types of planar mechanism with less than 12 bars. And take the 6-member single active member mechanism motion chain as an example to carry on the type synthesis.
