Abstract：With the continuous improvement of coal mine safety production requirements,mine-used flameproof power equipment,as a key component of the underground electrical system in coal mines,has its shell design and pressure resistance performance directly related to the safe and stable operation of the equipment.The study aims to explore the design principles and pressure resistance performance of the shell of mine-used flameproof power equipment.By combining theoretical analysis,simulation verification of the strength of three commonly used reinforcement ribs,and experimental verification,an in-depth study was conducted on the pressure resistance performance of the power equipment shell.A design method for the power equipment shell that combines thin plate theory with finite element analysis was proposed.This method can effectively predict and optimize the pressure resistance performance of the shell.The pressure resistance and sealing performance of the box shell were verified through a 1.5 MPa water pressure test,and no plastic deformation was observed after withstanding high pressure for 1 minute.The research results have important theoretical and practical value for improving the safety and reliability of mine-used flameproof power equipment.
