The results of Assur group model synthesis and number synthesis are briefly discussed, a combination of kinematic chain characteristic value is used to marker the result of number synthesis. Based on the analysis of kinematic chain characteristic value expression, the data rang of mutiple components or multiple joints, binary component and the key points and so on are analyzed and discussed. On the basis of above analysis, the number synthesis method of planar kinematic chain is proposed based on the dichotomy. With high computing efficiency, all the number synthesis results for 4~10 component...
