摘　　要：为跳马项目研究的电测系统中引入数字信号处理的传递函数及频谱分析的方法,采集和处理了因人体冲击三维力对信号的耦合干扰造成的十分复杂的响应信号,具有较高的动态测试精度.可以获得跳马动作的全部运动生物力学参数.现已用于中国国家体操队进行计算机辅助训炼.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.
