摘要

摘要: 针对某煤矿井下救生舱，利用ANSYS和LS-DYNA软件建立救生舱、瓦斯/瓦斯煤尘和巷道三维有限元模型。分别进行了真实内瓦斯/瓦斯煤尘爆炸作用下救生舱流固耦合数值分析，等效三角波爆炸冲击荷载作用下救生舱动态模拟和静水压力荷载作用下救生舱的极限承载力和极限变形的数值计算，确定救生舱动/静态承载能力变化规律和变形模式，给出瓦斯/瓦斯煤尘爆炸超压与救生舱承载能力和变形模式的变化规律。研究结果表明，等效三角波爆炸冲击荷载作用下该救生舱整体结构的极限超压明显比流固耦合计算分析结果大，流固耦合计算分析结果更接近于实验结果。该救生舱满足爆炸冲击波荷载下的变形要求时，其在静水压荷载作用下的变形也能满足。

Abstract: In this work, by using the ANSYS and LS-DYNA softwares, we established the three-dimensional finite element model of the refuge chamber, the gas/gas and grime and the laneway. The ultimate strength and deformation of the refuge chamber were simulated under the action of three kinds of loads, mainly including the fluid-solid interaction numerical analysis of the real gas/gas and grime explosion effect, the equivalent triangle wave explosion numerical dynamic simulation and the hydrostatic pressure load calculations. Through the above three forms of numerical simulations of loading, we determined the dynamic/static load capacities of the refuge chamber as well as the deformation rules with the given gas/gas and coal dust explosion overpressure variation. The simulation results indicate that the limit overpressure of the refuge chamber under the equivalent triangle wave explosion is bigger than the fluid-solid interaction numerical analysis results, which approaches more closely to the experimental results. If the refuge chamber can meet the demand of transformation under explosion loading, it can also satisfy the transformation requirement under hydrostatic pressure load.
