| 摘 要： | 将着服装人体简化为11刚体模型,参考Morison公式引入水动阻力,基于多体动力学软件ADAMS建立了航天员水下动力学模型。进行了试验并根据试验记录对模型进行了修正。通过模型仿真与试验录像处理得到的运动学数据进行比较来验证模型的有效性。在水下环境和空间环境的的仿真数据基础上,讨论了配重,水动阻力和浮漂反馈对肩关节和膝关节力矩的影响。

| Abstract: | An eleven-segment model was developed using the multibody dynamics software ADAMS to study suited human motions underwater. The modified form of Morison's equation was used to evaluate the hydrodynamic resistance. An experiment was implemented and the model was modified by the experimental record. Then the simulation result was compared with the kinematic data extracted from video image processing to validate the model. The influence of the ballast, hydrodynamic resistance and float on shoulder and knee joint torques was discussed through simulations in underwater and real space environment. |
