| 摘 要： | 提出了一种基于力矩比优化的航天员人体运动控制算法,该算法综合考虑了反向运动学、反向动力学以及人体工效学等因素,避免了单纯从动力学方面求解所带来的虚拟人体动画所隐含的力量冲突,提高了仿真结果的真实性和合理性。研究结果可为航天员舱外活动的设计和考察提供一定的理论指导和技术支持。

| Abstract: | An algorithm based on taking into account the torque ratio is proposed for simulating the extravehicular activity. The algorithm, which integrates inverse kinematics, inverse dynamics and human ergonomics information, avoids the collision between the human position and strength produced only using the dynamics or kinematics. It enhances the accuracy and reasonability of simulation. The simulation result can provide some guidelines for the design of extravehicular activity and ground training of astronauts. |
