Application of Vibration Testing Technology in Table Tennis Ball Land Point Location

Statistics is very important for table tennis (TT) players, coaches, referees, even TT fans. But now it is an extravagant hope because there hadn't been any statistics for a TT match. The basic elements of TT is strength, speed, spinning and landing point. In order to implement the TT landing point location, this paper designs a set of experiments to study the relationship between ball landing and responding of TT table in the circumstances of the same excitation strength and different landing points, different excitation strengths and the same landing point, as well as floor vibration interference etc.. Selects the piezoelectric acceleration sensor to pick up the ball table vibration signal, data acquisition through the oscilloscope, the vibration signals is analyzed in time and frequency domains in Matlab. The achievement laid a sound foundation for accurate locating TT ball landing point.
