Finite Element Analysis on Protective Airtight Doors of Mine Removable Rescue Capsule

In this paper, a cured door structure of mine rescue capsule is proposed, and compared with ordinary flat panel doors. Firstly two kind of three-dimensional solid models of mine removable protective airtight doors are established by the Pro/e software. And then take the advantage of the strength analysis of ANSYS finite element software to draw the stress and strain diagrams. The analysis results show that the strength and stiffness of the curved door is better than ordinary flat panel doors, which provide important theoretical basis and reference value on the design, research and dynamic analysis of the life-saving door.
