速度投影定理的补充与应用

Supplement and application of the velocity projection theorem

本文对刚体平面运动速度投影定理的内容进行了补充,利用补充后的速度投影定理,不仅能求解刚体平面运动时任意点的速度,而且还能求解刚体平面运动时的角速度.

This article provides an addition to the theorem of rigid body velocity projection. The supplemented theorem can be exploited to work out the arbitrary speed of the rigid body in plane motion. It can also be used to figure out the angle rate of the body in plane motion.
