| 摘 要： | 在满足结构强度要求下，严格控制车体重量是空降特种车辆总体设计中需要把握的重要设计准则。通过试验研究简化了着地冲击过程仿真，建立了铝合金车体和焊缝的有限元模型；采用大位移、非线性、动态有限元方法，对于车体着陆过程进行了瞬态有限元结构强度分析和模态分析，得到了不同着陆状态下，车体位移、应力和应变的瞬态分布结果；验证了该有限元模型和分析方法的有效性，为车体结构的优化设计提供了可靠依据。

| Abstract: | It is the most important R&D criteria for airborne armored vehicle to optimize the hull structure assured of both strength and weight control.The structure analysis simulation depends on the data of vehicle airborne test.The finite element model for the aluminum alloy body and its welded joint was built.The landing process of the vehicle was simulated by dynamic nonlinear finite element method.The transient results of displacement,strain and stress under normal,worse and worst airdrop conditions were obtain... |
