平面运动刚体瞬心的分析及应用

Analysis and Application of the Instantaneous Center for Rigid Bodies in Plane Motion

分析了刚体平面运动中的速度瞬心与加速度瞬心,总结了确定它们的方法,并用实例说明了对速度瞬心和加速度瞬心的动量矩定理在解决一些问题时能使问题简化。

The instantaneous center of velocity and the instantaneous center of acceleration for rigid bodies in plane motion are presented in this paper, and some methods of ascertaining are given, using the theorem of momentum moment of instantaneous center of velocity and acceleration can simplify in some problems.
