ABSTRACT Based on the studying on barrier device of gas explosion, an optimized design scheme of gas explosion barrier door with foam ceramics as the main body is proposed. The author uses ANSYS software and finite element method to simulate and compare the main performances of four typical doors in thickness, such as uniform thickness, thick in the upper and thin in the lower, thin in the upper and thick in the lower, secant circular. Results of simulation reveal that the moistest stability and good withstand voltage in structure dose the secant circular door have, describe optimization in detail and provide a feasible optimization of barrier device of gas explosion. [Pg.439]
