| 摘 要： | 通过求解球与定轴转动杆完全弹性碰撞过程的非线笥动力学微分方程组,研究了碰撞过程中动能与压缩变形能之间的相互转换。得出了碰撞始末球的平动动能与杆绕定轴的转动动能之和明显不守恒的结论。

| Abstract: | By solving the nonlinear dynamic differential equations in perfect elastic collision process between a ball and a bar rotating about a fixed axis,this paper deals with the transformation of the kinetic energy and the potential energy of compressive deformation in the collision process.It has been concluded that the sum of the kinetic energy of the ball and the rotational energy of the bar is strikingly unconservative. |
