摘要:
救生球在煤矿井下的灾害救援中具有重要的作用,其抗爆性能直接决定了救援的效率。在多孔复合材料基础上,采用LS/DYNA软件建立了3种不同复合结构的救生球,基于ALE算法考查了3种救生球结构在瓦斯爆炸作用下的动态响应,分析了各结构的应力场、位移场及能量变化特征,计算了不同复合材料对结构可靠性的影响。结果表明:多孔复合材料增强了整体结构的抗爆性能,泡沫铝的缓冲性能优于聚氨酯。
Abstract:
Abstract:Rescue ball plays an important role in rescue for coal mine disasters,and the antiknock performance of rescue ball directly determines the efficiency of rescue.We establish three different composite structure of rescue ball based on porous composite materials using LS/DYNA,and ALE algorithm is employed to examine the dynamic response of those 3 balls with underground gas explosion blast load.The stress field,displacement field and energy variation laws are analyzed,and the influence of different composite materials on the structural reliability are calculated.The results show that the porous composite material enhances the anti explosion performance of the whole structure,and the cushioning performance of aluminum foam is better than that of polyurethane.
