基于ANSYS/LS-DYNA非线性有限元显式动力分析软件,建立了移动救生舱有限元模型;采用非线性、动态有限元方法,对正面受到爆炸冲击载荷作用下移动救生舱的动力响应进行了数值模拟,并得到了不同时刻下救生舱位移、应变和应力的瞬态分布结果及移动救生舱的破坏过程。模拟结果表明了在近距离爆炸空气冲击波荷载作用下,救生舱发生的破坏形式,为舱体结构的优化设计提供了可靠依据。 Based on the ANSYS / LS-DYNA nonlinear finite element explicit dynamic analysis software, the finite element model of the mobile rescue capsule was established. The dynamic response of the mobile rescue capsule subjected to the explosive impact load on the front was analyzed by nonlinear and dynamic finite element method Numerical simulations were carried out and the transient distribution of displacement, strain and stress of the life-saving tank at different times and the failure process of the mobile life-saving tank were obtained. The simulation results show that the damage form of the rescue cabin under the impact of short-range blast air shock wave provides a reliable basis for the optimal design of the cabin structure.
