瓦斯爆炸载荷作用下矿用柱壳救生舱抗爆性分析及结构优化
Antiknock analysis and structure optimization for coal mine cylindrical shell refuge capsule under gas explosion load
摘要
Abstract
Coal mine rescue capsules are an indispensable equipment for safe production and effective rescue in coal mines,and their efficiency and stability directly determine the rescue efficiency and the antiknock performance in coal mines.In this paper,a cylindrical shell rescue capsule was designed to guarantee the stability of the capsule under a gas explosion load.Firstly,the load of the explosion field was simulated using ANSYS/LSDYNA and validated with previously reported data.Secondly,the coupling effect between the flow field of the explosion shock wave and the rescue capsule was revealed using the ALE fluid-structure coupling algorithm in real coalmine conditions.Thirdly,the antiknock performance analysis and structural design optimization were conducted on the original model.Finally,the dynamic response,strength and energy variation were compared for the original model and the optimized version qualitatively and quantitatively.The results show that the antiknock performance of the optimized model has reached the required national standards of China.关键词
