摘要
目的通过仿真给出水下训练航天服的固定配重设计。方法基于水下训练航天服3D模型数据,参考人体国标参数,对照俄罗斯水下训练服,利用组合物体的力学性质,考虑水下训练航天服的实际应用,仿真分析固定配重对水下训练航天服姿态的影响。结果经过多参数计算仿真,最终确定水下训练航天服的固定配重参数。结论水下训练航天服设计仿真解决了固定配重的设计难题,对水下训练航天服的实际应用有一定的指导作用。
Objective To design the fixed balance weight for underwater training spacesuit by simulation.Methods According to the 3D underwater training spacesuit model,human body parameters from the national standard,the similar Russian spacesuit,mechanics characteristic of the complex,and the actual application,the influence of the underwater training spacesuit pitch angle due to the fixed balance weight was simulated. Results The fixed balance weight data were calculated by simulation with multiple parameters. Conclusion The simulation solves the difficult design problem of the fixed balance weight. It can serve as a reference for the actual application of the underwater training spacesuit.
