| Abstract: | When plane motion of a planet wheel is decomposed as rotation of the planet wheel relative to a rotating reference frame and rotation of the rotating reference frame relative to a stable reference frame,a new method to evaluate the angular momentum is presented in this paper.The present method shows that angular momentum of the planet wheel about a fixed axis is equivalent to transport angular momentum and relative angular momentum.The method is definite in physical concept and convenient for implementation. |
