摘要：

为确定乒乓球拍胶皮橡胶硬度对球体撞击特性影响，采用有限元分析方法对不同橡胶硬度条件下乒乓球撞击胶皮过程进行分析，比较不同橡胶硬度胶皮在球体不同撞击速度时的接触时间、胶皮最大变形量变化，探讨胶皮橡胶硬度与乒乓球撞击特性之间的规律。结果表明：球体与球拍胶皮接触时间为毫秒量级。在胶皮硬度较低时，接触时间、胶皮最大变形量均随胶皮硬度增加而缩短。在高速、高硬度情况下，由于球体自身变形影响，接触时间略有增加，最大变形量位置也发生改变。该研究对球拍胶皮的设计、制造与测试具有一定参考价值。

Abstract: For determining the effects of rubber hardness on the impact characteristics of the ball, the finite element analysis method was used to analyze the impact process of the pingpong ball on the rubber when the rubber hardness changed. The contact time and rubber maximum deformation were achieved with different impact speed of the ball and the relationship between the hardness of rubber and the impact characteristics was analyzed. Results show that the contact time is on the order of milliseconds. Increasing the racket rubber hardness could shorten the contact time and decrease the racket deformation under low rubber hardness conditions. In the case of high speed of the ball and high hardness of the racket, the deformation of the sphere itself caused a slight increase in contact time and the position of the maximum deformation would change. It is useful for design, manufacture and testing of table tennis racket.
