摘要

The door of coal mine mobile refuge chamber should keep strong structure during its life cycle. A basic structure of the door was designed. And finite element models of the door were established for numerical simulation, with thickness 10, 20, and 25 mm, respectively. Finite element software ANSYS/LS-DYNA was used in the numerical simulation. Deformation of the door under a triangle explosion shock wave with maximum value for 0.6 MPa and 300 ms duration was calculated. The maximum stress value appears in the connection position between the door plank and reinforced stiffeners. The maximum displacement value appears in the middle of the door plank. Stiffeners have significant effect on the maximum displacement. The maximum displacement of improved chamber door is reduced to 5.25 mm, having a decrease of 19.22 mm. According to the simulation analysis, the door with 20 mm thickness could fulfill the requirements of structure safety.
