摘　　要：使用有限元软件ANSYS Workbench中AUTODYN求解器对某压药防爆间进行了爆轰仿真分析,获得了防爆板厚度与其防爆性能间的定量关系。结果表明:防爆板厚度与TNT的极限工作药量成二次几何关系。14 mm厚的Q235钢防爆板可承受TNT的极限工作药量为170 g,30 mm厚可承受极限工作药量为475 g,同时给出了防爆板厚度与TNT极限工作药量的关系式,研究结果可为同类型防爆间的设计选型和防爆性能验证提供理论指导。The detonation of an explosive explosion-proof room was examined by finite element software ANSYS Workbench with the AUTONDYN solver.The quantitative relationship between the thickness of anti-explosion plate and its explosion-proof performance was studied.Results show that the thickness of anti-explosion plate has a quadratic geometric relationship with the limit equivalence charge of TNT.The limit equivalence charge of 14 mm Q235 steel plate is 170 g,and 30 mm is 475 g.The quantitative calculation formula between the thickness of the anti-explosion plate and the limit working charge of TNT is proposed.The results can be utilized to provide theoretical guidance for the design and verification of explosion-proof rooms.
