煤矿救生舱的爆炸模拟分析

煤矿救生舱将成为矿工井下逃生的重要设备,其结构强度直接决定了矿工的生命安全。为提高救生舱强度,在ABAQUS环境下建立了救生舱的有限元模型,使用显式积分方法得到了在煤矿瓦斯爆炸时的压力对救生舱的影响。救生舱的最大应力出现在角落应力奇异处及肋板中部部分区域并达到了屈服强度,但救生舱的总体应力大小在允许范围之内。

Explosion Simulation and Analysis of Coal Mine Rescue Capsule

Coal mine rescue capsules,whose structural strength defines miners’ safety directly,are becoming important equipments for miners’ underground escaping.In order to improve the rescue capsule’s strength,in this study the finite element model was established in ABAQUS environment,and the influence on rescue capsule made by the pressure of gas explosion was obtained by using explicit integration method.The maximum stress of rescue capsule appears at the corner where it has stress singularity and the central part of the stiffeners where the stress reached the yield strength.But the overall stress is within the allowable range.
