人体运动环节质量矩测量仪的研制

The development of measuring instrument for the moment of mass of moving segment of human body

人体运动环节质量矩是环节质量与环节质心位置的乘积 ,反映了人体环节的质量分布情况 ,是运动人体科学研究的一个重要指标 .利用现代的传感器技术和计算机技术 ,研制了人体运动环节质量矩测量仪 ,并分别系统地介绍了该仪器的测量原理、机械部分、电子部分和计算机软件部分 .利用该仪器对运动环节质心与人体总质心之间存在的联动关系进行了实验验证 .

The moment of mass of segment of human body is the product of mass of segment multiplying the location of center of mass, which reflects the distribution of mass of segment, and is an important parameter in the study of moving human body science. In this study, a measuring instrument for the moment of mass of moving segment of human body is developecl by applying modern techniques of transducer and computer, and its mechanical part, electronic part and its software part as well as its measuring principle are introduced in detail. The linkage relationship between mass center of moving segments and mass center of human body are validated by experiment.
