摘　　要：乒乓球拍作为主流体育运动器材,其底板材料特性直接影响击球过程中的球速及旋转变化。为更好研究乒乓球拍底板材料对击球的影响,建立底板球拍与乒乓球碰撞模型,采用不同复合材料模拟乒乓球与不同材质底板的碰撞过程,通过研究乒乓球与底板相对速度及碰撞接触时间,分析复合材料乒乓球拍的动力学特性。结果表明:较之桧木,阿尤斯木底板球拍的反弹速度提高了22%,即增加碳纤维材料可提高出球速度;随着入射速度增加,相同底板材料下碰撞过程能量损失增加,碳纤维材料提高能量转化率,增加碰撞高速球的适应性;此外,当球速为20m/s时,碳纤维阿尤斯木底板球拍下乒乓球反弹速度比桧木底板球拍高32%;较之碳纤维阿尤斯底板,碰撞接触时间乒乓球入射速度增大而减小,且相同入射速度,与桧木底板碰撞接触时间可增加44%。The paddle is the source of table tennis,fundamentally determining the speed and spinning performance of the ball.In order to analysis the performance of table tennis,We establish table tennis collision model with different paddle material,analyze the process of collision and compare the rebound speed and collision time of table tennis at different incident speed based on numerical simulation.Conclusions are as follows:compared to Hinoki,the rebound speed of Ayous table tennis racket increases 22%,and can be improved while added carbon fiber;more energy losses during the collision process under higher incident speed when the paddle materials are the same.While the incident speed is 20 m/s,the rebound speed of Ayous with carbon fiber increases 32%compared to the Hinoki.When the material of paddle is the same,the collision contact time decreases as the incident speed increases.Under the identical incident speed,the collision time of Hinoki grows more than 44%.
