摘　　要：研制了一套便携式多功能人体重心位置动态检测系统,该系统包含1个5支点测力平台、4个压力传感器、1个数据采集卡以及1个PC计算机,其中,测力平台由主件、附件、延伸件等组成。通过对主件及附件14个点位3种不同负荷加载下压力中心位置的测试表明,宽度方向的精度在1mm以内,而长轴方向精度平均在3mm左右。现场测试表明,该系统能满足站立、卧姿等人体多功能实验测试的要求,可以为体育教育与训练、运动员选材、全民体质检测、医疗康复等方面服务。This paper developed a potable multi-functional determination system of dynamic human body center which includes one force platform with five fulcrums, four force transducers,one A/D card and one PC computer. The force platform was made of one main, an additional and one extending parts. Through testing fourteen points with three kinds of weight on the force platform, the author found out that the error in width was lower than lmm with about 3mm average in long axis. For human performance tests,the result showed that this system could meet the need of the multi-functional determinations including standing or prone position and could be used in many areas such as physical education ＆ training,sport talent selection, national physical fitness determination and medical recovery.
