长胶乒乓球拍击球瞬间弹力实验分析

运用小型测力机对长胶粒进行实验分析，并采用乒乓球发球机，分别用长胶和反胶在相等力作用下，对击出球的回球线路实际观测进行比较。结果表明：外力将球体压至长胶粒根部时反弹力为最大值，而当外力将球体压触根部以上时，柔韧长胶粒会造成外力损耗，反弹力较小；长胶用推挡力时，回球线路突陡，出现“下沉”状态；而长胶斜向用力时，回球则出现飘忽不定的状态。

Analysis of Bounce on Long Pbnpled Rubber of Table Tennis

Applied the small apparatus to test force and fast camera and robot machine,the different track is compared by using long pimpled rubber and inward sandwich lubber in the same condition of hitdng.The results indicate: as the outside force is coming the root of long pimpled rubber, the bounce is the max. In other condition, the bounce changes gradually weak.The moving track of table tennis immediately pushes with long pimpled rubber.The main reason is related to the angle of hitting table tennis with different pimpled rubber.
