Abstract

Aiming at the technical problems of pressure resistance, explosion resistance and structural optimization of the safety refuge device, the cabin structure of the safety refuge device was parametrically modeled, and a new triangular cabin structure model was established. Loads were applied to the established triangular cabin, and static analysis was performed using ANSYS Workbench to observe the stress and deformation distribution of the cabin. Taking the quasi-triangular cabin structure as the research object, the optimized mathematical model of the cabin is established, and the equivalent stress, total deformation and quality of the quasi-triangular cabin are multi-objective optimized by using Creo and AWE joint simulation. The optimal solution of the quasi-triangular cabin structure is found through DOE optimization method. The analysis results show that: under the premise of unchanged cabin mass, the optimized cabin stress and total deformation are relatively reduced a lot, achieving the purpose of cabin optimization design, meeting the overall design requirements of the safety refuge device, and providing effective theoretical basis and technical support for the design and manufacture of the safety refuge device.
