求曲柄滑块机构滑块加速度的速度瞬心法

The velocity instantaneous centre method for finding the acceleration of slider in crank-slider mechanism

用速度解心法求机构的速度是非常方便和直观的，但用它来求加速度及角加速度则没有资料介绍。本文介绍了用速度瞬心法求解曲柄滑块机构滑块加速度的方法，并给予论证。

It is very convenient and audio-visual for finding the velocity of mechanism by the use of ,velocity instantaneous centre method but there is no material to introduce how to find out acceleration and angula acceleration by adopting that method.This paper introduced a way for finding the acceleration of slider in the crank- slider mechanism by the use of velocity instantaneous method,and gave out the demonstration.
