摘要
将牛顿摆简化为球链并看作弹簧-质量系统,基于无量纲动力学方程组对球链上小球的运动特征进行数值分析.结果表明,入射球速度、球材料特性以及球半径等因素均影响球链上的动量和能量传递效率.
Simplified the Newton′s Cradle to ball-chain and considered the balls as a model of mass-and-spring,the motions of the balls are analyzed numerically by use of the non-dimensional equations.The results show that many factors affect the efficiency of the transmission of the momentum and energy in the ball chain of Newton′s cradle,such as inclined velocity,the property of the material and the size of the balls.
