摘要: 航天员在自由状态下的转体技术是航天员训练和太空任务完成好坏的重要指标。本文借助15段的人体模型,使用多刚体动力学的方法建立起航天员转体动作的力学模型。该模型易于编程,适合于实时计算。并使用计算机动画技术,建立了航天员转体运动的实时动态仿真系统。该系统只要求输入基本的人体测量数据和肢体的相对运动规律,以图形动画形式输出,具有良好的交互性。

Abstract: During space performance,proficiency in self rotation may conceivably serve as a criterion for crew selection.By using a body model of 15 segments and dynamics of rigid bodies,the astronaut's self rotation is modeled.The model suits for programming and computation in real time.An animation system has been built to simulate the astronaut's self rotation in real time.only anthropometric data and limbs' rotations are required as input.The system works interactively and draws dynamically.
