摘 要: 刚性连接两质点球系统是理论力学教学中一种力学模型.流行教参对该问题讨论不多,容易造成对刚性连接两质点球系统的运动学问题不正确的理解.笔者尝试从刚体的基本性质出发,导出刚性连接两质点球系统在运动中所具有的特性:两质点在沿杆方向上的动量分量和受到的冲量相等,并利用这些特性解决刚性连接两质点球系统运动问题. Two rigid joint particle sphere system is the mechanics model of the theory mechanics. But not much discussion has been found in the reference books, which leads to the misunderstanding about the kinematics problems of the rigid joint particle sphere system. The author tries to educe the characteristics in motion of rigid joint particle sphere system from the basic character of rigid body: the momentum and impulse are equal along the pole. Applying these characteristics, we can resolve the motion problems of rigid joint particle sphere system.
