Abstract

Table tennis spiking point position geometric mechanical features research

Author(s): Xiaopei Jiang

According to Geometric principle, it establishes table tennis spiking model, according to high hitting and low hitting differences, it gets ball trajectory figure and dropping points position, by establish Lagrange equation, the paper gets restricted particle dynamical equation, and gets shoulder point and elbow point moment of force Mh and Mk. Then according to hitting points to net surface vertical distances differences, it gets table tennis drop points differences, six different hitting points lowest points landing data through net in the degree of 45° and 30°. When athlete spikes, he should try to manage to stretch arms to right ahead and remain vertical to hitting point, athlete take-off height gets higher, and ball over net probability would be larger.
