Abstract: We carries out the 3D solid modeling and explosion shock wave calculation for the selected refuge chamber, obtains the explosion shock wave data, finite element calculation for the whole refuge chamber and single cabin is carried out respectively on the basis of the load conditions, then strength and deformation results are compared and analyzed under these two conditions. The conclusion shows that finite element calculation result of single cabin is roughly the same with whole refuge chamber, especially the strength result is consistent, and so it could reflect the intensity level of the whole cabin. In order to reduce the modeling and calculation time, single section cabin result could be taken as a reference of the refuge chamber initial design and calculation, which can help the designers to find out the weakness of rescue capsule and guide subsequent design work.
