以优化载人飞船气囊缓冲综合性能为目的,建立了载人飞船环形组合气囊缓冲过程的简化模型,以最大过载、终端触地速度、气囊初始充气质量为目标函数建立了多目标优化模型,采用多目标遗传算法进行求解。计算结果表明该方法能在有效降低终端触地速度的同时,兼顾最大过载及气囊初始充气质量,从而达到气囊缓冲综合性能优化的目的。
Aiming at the optimization of the airbag cushioning performance of a manned spacecraft, a simplified model of the cushioning process of the manned spacecraft combined balloon was established. The multi-objective optimization model was established with the objective function of maximum overload, terminal touchdown speed and airbag initial charge. Multi-objective genetic algorithm to solve. The calculation results show that this method can effectively reduce the touchdown speed of the terminal while taking into account the maximum overload and the initial inflation quality of the airbag so as to achieve the objective of optimizing the airbag cushioning performance.
