平面机构高副低代原理的证明

THE PROOF OF THE PRINCIPLE OF A HIGHER PAIR REPLACED BY LOWER PAIRSIN A PLANE MECHANISM

证明了机械原理中传统的高副低代方法可保证此高副机构和它的低副替代机构自由度不变、瞬时速度和瞬时加速度不变。

The traditional method of a higher pair replaced by lower pairs is proved to be able to guarantee the mechanism with higher pair and its equivalent lower pair mechanism have the same freedom,instantaneous velocity and instantaneous acceleration.
