本文阐述了以杆组为基础的机构运动分析和动力分析的解析方法,提出了按杆组类型建立相应的算法,构造子程序快。不同子程序组合、调用,可以解决复杂机构的分析问题,从而扩大了解题能力,使程序具有通用性,并可获得较快的计算速度。用这种方法编制的源程序,对一般机械及农业机械平面杆机构的分析都是适用的。 In this paper, the analytic method of kinematic analysis and dynamic analysis of the mechanism based on the rod group is expounded. The corresponding algorithm is set up according to the rod group type, and the subroutine is constructed quickly. The combination of different subroutines and calls can solve the analysis problems of complex institutions, so as to expand the problem-solving ability, make the programs universal and obtain faster calculation speed. Using this method of preparation of the source code, the general machinery and agricultural machinery plane lever body analysis are applicable.
