| Abstract: | The method of transfer function and frequency analysis in digital signal processing is introduced in strain measurement in this system.This system has high accuracy in picking up and pro- cessing very complicated response signals caused by interference of sensors in three directions.Al- though the natural frequency of the structure is lower than the frequency of impacting forces of human body.This system is useful not only in giving all sports biomechanics parameters of actions of vaulting horse,but also in making similar system used for measuring multidimensional forces in real-time of low frequency system.This system is used now for computer-aided training by Chinese Gymnastics Team. |
