摘　　要：该文提出了求解平面机构瞬心速度的广义三心定理和瞬心速度图的概念 ,指出了瞬心速度图与瞬心图的同构关系。给出了应用瞬心速度图的邻接矩阵自乘求解机构全部瞬心速度及求解给定瞬心速度最短路经的方法。The generalized Aronhold-Kennedy theorem for solving instant center velocity (the moving velocity of instant center position) of planar linkages and the instant center velocity chart is introduced. The isomorphic relationship between instant center velocity chart and instant center chart is indicated. Finally, the methods to find all instant center velocities and the shortest path leading to any instant center velocity of a mechanism using square adjacent matrices are explained.
