摘要
该文深入研究了人体空中运动的11刚体人体多刚体模型,利用该模型可以计算出人体各环节的质量、质心位置以及沿过质心的三个正交轴的转动惯量,同时还讨论了该模型用于人体空中运动模拟时角动量及外部方位角的计算方法。在此模型基础上,开发了人体空中运动模拟系统,开发过程中使用MATCOM实现MATLAB和V isual C++的混合编程。最后将真实人体及其跳水过程中通过摄像系统获取的一组实测数据代入系统进行计算,计算结果与真实值比较接近,在误差范围之内。
The 11 linked rigid segments model of human airborne movement has been investigated. The mass, location of mass centre and principal moment of inertia about orthogonal axes through the mass centre of each segment could be calculated. Calculational methods of the angular momentum and the whole body orientation angles in this model have been discussed in detail. The simulative system based on this model has been successfully developed by the mixed programming of MATLAB and VC ＋ ＋ with MATCOM. At last, the data obtained from the actual measurement of the body and the ,diving procedure were used as the program parameters and the corresponding results were briefly analyzed. The results were in the range of error and neared the true value.
