Mine Explosion-proof Cabinets To Optimize The Design

ShanXi is a big province of coal. The environment of coal is execrable and there isoften some hidden trouble. So it is easy to occur accident. If there is a triangle ofexplosion(kinding, oxygen environment, flammable gas or kinding, oxygen environment,coal power),it is easy to occur explosion. So it has realistic meaning to design a systemof coal well explosion-proof cabinet with high efficiency and security.This paper use the technology of finite element method to study on the coal wellexplosion-proof cabinet and is under the idea of explosion-proof design.The technology of the finite element method (FEM) has been a strongcomputational implement in the engineering design field. It increasingly became matureand practical in the past half century. And it is more and more important in all kinds ofthe engineering design field. This paper uses the advanced finite element method to analyze the explosion-proofcabinet and sets up a three-dimension model with the tetrahedron element by 10 nodes. Itis analyzed respectively through the linear static and nonlinear methods。 The analytical result indicates that the stress distributing of thetransformer-cabinet is uneven, the stress value in the plank and the conjunction part islarge and varied greatly. The stress value in the other part is all lower and there is certainstrength storage. The area of biggest deformation occurs in the center of the plank.By testing research on the spot, it verifies the correctness and reliability of the FEMmodel, and it provides reliable data and technical storage for further researching. Basedon above analysis, the author improves the design of the explosion-proof cabinet andpresents kinds of projects. By the finite element method, the best project is gotten.After analyzing the stress and deformation by FEM, this paper proves that FEM hasa strong vitality. As long as a calculation model can be built up correctly, and the loadcircumstance and the boundary conditions can be properly simplified, an analysis can becarried on. As an assistant means, FEM has improved on the design work and got rid ofthe past experiential design method.
