平面连杆机构分析与仿真专家系统

ANALYSIS AND SIMULATION EXPERT SYSTEM OF PLANAR LINKAGE MECHANISM

任意平面连杆机构，在拓扑组成上，可表示为无向图，本文研究了从机构无向图出发建立机构运动生成链和分离可独立求解杆件组，建立规则库自动按照约束性质生成约束方程式和采用变异几何方法数值求解机构运动。本文介绍了一个按上述原理实现的任意连杆机构分析仿真专家系统。

The topology of a planar linkage mechanism can be represented as an undirected gragh. This paper deals with generating the movement propagation chain and separating solvable link groups from a mechanism graph,establishing rules for automatic generating constraint equations corresponding to existing constraint conditions and calculating the kinematics by variation geometry methord. A prototype software for analysis and simulation of planar linkage mechanism based on the above approach is also introduced.
