| 摘 要： | 本文籍助图论提出了“速度瞬心网络图”和平面机构待求速度瞬心的可解性条件,依此可迅速判定多杆平面机构待求速度瞬心集的求解顺序,避免盲目试碰;另外,网络图与相对运动图解法结合得出了求解二自由度平面机构速度瞬心的一种可行方法,这类机构的速度瞬心单纯采用三心定理是不可能求解的。

| Abstract: | With the help of graph theory this paper brings out "net graph of velocity instant centers" and the resolvable conditions of unsolved velocity instant centers of plane meehanisms, by which a soluble sequence of unsolved velocity instant centers of multiplicate bar plane mechanisms can be found rapidly so as to prevent aimless trial and error. In addition a feasible method of finding out velocity instant centers of plane mechanisms for two degrees of freedom can be obtained by means of combining net graph with graphical relative motion method, which is impossible to be solved by only the Three Centers Law. |
