瓦斯爆炸产生的强大的爆炸冲击波会使救生舱板壳结构发生一定程度的塑性变形,甚至发生倾倒和扭曲,破坏严重时将失去保护作用。通过ANSYS/LS-DYNA对舱体结构进行了抗爆分析,为救生舱结构设计提供了有利支持。
The powerful blast shock wave generated by gas explosion will make certain degree of plastic deformation of the life-support board shell structure, even dumping and twisting. When the damage is serious, the protection effect will be lost. The ANSYS / LS-DYNA was used to analyze the structure of the cabin against explosion, which provided favorable support for the design of the rescue cabin.
