Abstract
Abstract: Aiming at the strength problem of the underground rescue cabin under explosion impact load, a finite element model of overall explosion impact load and fluid-solid coupling structure response is established in transient dynamic soft LS-DYNA. The flow field impact load is generated by explosion algorithm, and the propagation of the impact load in the air is calculated. The dynamic response of the rescue cabin structure under the impact load is calculated by the fluid-solid coupling method. The results show that the maximum load occurs on the end surface closest to the explosion source, and the structural deformation is small because the end surface is small, and the maximum deformation occurs on the side wall of the cabin. The established finite element model covers the whole process of the explosion and shock of the cabin, and the results are more accurate. It has a certain engineering value for the development of rescue cabin.
