论文摘要
线性仪表盘模型应用于刚性表面上的单个球弹跳。结果表明,与先前忽略重力作用的工作相反,重力恢复的系数取决于冲击速度。在低冲击速度和高阻尼时,这种速度依赖性最为明显。当压缩为非零时,先前的工作认为球与地板接触,而其他分析则终止了碰撞,以防止吸引力。我们比较这些模型,并提出两者之间的混合体。混合模型成功地重现了在春季反复反弹的车的实验结果。
The linear dashpot model is applied to a single ball bouncing on a rigid surface. It is shown that when gravity is included the coefficient of restitution depends on impact velocity, in contrast to previous work that ignored the effects of gravity. This velocity dependence is most pronounced at low impact velocities and high damping. Previous work has considered the ball to be in contact with the floor when the compression is nonzero, while other analysis terminates the collision earlier, to prevent an attractive force. We compare these models and propose a hybrid between the two. The hybrid model is successful in reproducing experimental results for a cart bouncing repeatedly on a spring.
