Abstract: In order to test the anti-impact performance of the refuge chamber and verify the reliability of the experiment on the scaled model of the refuge chamber, the reduced-scale model and the original model of the refuge chamber were established in this paper. By using the finite element software ANSYS Workbench, the dynamic response results of the two models under impact loading are simulated and analyzed. The results show that the response results of the reduced scale model are similar to the original scale model. The response results of the reduced scale model of the rescue capsule under impact load can be used to reasonably and effectively reflect the response results of the original scale model of the rescue capsule.
