摘　　要：为了给空降车及其气囊的优化设计提供技术支持,采用有限元方法对空降车气囊缓冲过程进行仿真分析。计算了正常着地工况下的气囊缓冲过程,得到速度、加速度以及气囊内压等时间特性曲线。结果表明:空降车在该工况下着地速度小于3m/s,该气囊符合空降车着地的缓冲性能要求。车体加速度和冲击应力在误差许可范围内,验证了采用此种方法进行空降车气囊缓冲过程的虚拟测试是可行的。In order to offer technique support to optimization design of airborne vehicle and airbag,a model of airborne vehicle and airbag is established to simulate and analyze airbag cushion process based on finite element method.Airbag cushion process under the situation of landing normally is simulated.Characteristic curve about velocity,acceleration and press are given.The landing velocity of airbag cushion is less than 3m/s under the situation of landing normally.It proves the airbag accord with the request of ...
