| 摘 要： | 在研究法向冲击速度对圆板碰撞恢复系数影响的基础上,应用高速摄像系统对伴有旋转速度圆板的冲击行为进行了实验研究,分析了不同法向冲击速度下旋转角速度对碰撞恢复系数的影响.通过确定变形量系数与旋转角速度的相关性,应用数值解析方法得出了不同法向冲击速度及旋转角速度下的碰撞恢复系数,得到了旋转角速度与碰撞恢复系数的相互关系.结果表明,数值计算结果与实验结果具有良好的一致性.

| Abstract: | Based on the relationship between approach translation velocity and coefficient of restitution,the dynamic behavior of a rotating circular plate impacting on a plane block was investigated experimentally using a high speed camera system.The effects of angular spin velocity on the coefficient of restitution have been discussed for difference approach translation velocities.The relationship between coefficient of indentation and angular spin velocity has been discussed.The coefficient of restitution has been obtained theoretically by numerical method for different translation velocity and different angular spin velocity.The relationship between coefficient of restitution and angular spin velocity has been performed.The results indicate a good correlation between the numerical and experimental results. |
