摘　　要：目的:研制一种集成检测动态行走和静态站立的地面反力分析系统。方法:设计三维测力台检测地面反力,开发数据采集、计算和分析的专用计算机软件。结果:利用该系统不仅可以检测行走过程中三个方向的地面反力,而且可以检测站立时压力中心曲线,计算其动摇长度、面积等特征值。结论:在测试常规行走的三维测力台上增加测试平衡能力的功能,可以丰富设备的功能,提高设备的利用率。Objective：To develop a detecting and analyzing system of dynamic and static ground reaction forces when walking or standing.Method：A 3-D force platform for detecting the ground reaction forces and a special software for data acquisition,calculation and analysis were developed,Result：Using this system,the ground reaction forces in three directions during walking and the trace of center of pressure（COP） oscillation during standing on the platform can be detected. Some characteristic parameters such as the length and area of the trace of COP oscillation can also be obtained. Conclusion：After being added body balance test function,the conventional 3-D force platform equipment becomes much more functional and the application scope is extended.
