摘　　要：针对设备载人空投过程中乘员防护的问题,设计出一种对乘员人体进行防护的缓冲气囊座椅,并采用MADYMO软件建立了缓冲气囊座椅数值模型,模拟该设备载人空投着陆中缓冲气囊座椅对乘员的缓冲过程。以减少人体的颈部损伤和胸部损伤为优化目标,利用微型多目标遗传算法对缓冲气囊座椅的充气质量、排气孔面积、排气压差以及缓冲气囊护颈的充气质量进行优化。该优化设计不但可以减少气囊座椅设计实验次数从而降低实验的成本,而且在载人空投防护技术领域具有一定的实际工程意义。In manned equipment airdropping process,in order to improve ability of manned airdrop protection,an airbag chair to protect human body was designed.A numerical model of airbag chair was established and the buffer process of the airbag chair to the human in airdrop landing was simulated with MADYMO.A multi-objective optimization method based on the micro multi-objective genetic algorithm for the dynamic characteristics of an airbag chair was proposed.An optimization procedure based on the micro multi-objective genetic algorithm was proposed to search the key parameters,such as,the air quality of the airbag chair,the venting area of the airbag chair,the venting pressure of the airbag chair and the air quality of the airbag for neck.The optimal design of the airbag chair could not only reduce test number and test the cost,but also have a practical meaning in fields of other manned airdrop protections.
