中文摘要:加筋板在船舶建造中具有广泛的应用,对其开展抗爆性能研究,有助于提升舰船生命力。本文以加筋板为研究对象,设计开展爆炸试验,对平面冲击波载荷持续作用下加筋板的爆炸响应进行研究。根据试验结果,提出了冲击波压力随标度距离和载荷持续时间的经验表达式,并利用该公式进行了数值模拟,发现计算结果与试验结果吻合较好。结果表明,在加劲肋的作用下,结构在不同方向的抗爆性能不同的。加强筋可以有效地提高加筋板的抗冲击性能。此外,本文还讨论了峰值压力大小对加筋板响应的影响,确定了加劲肋能承受的极限载荷。
英文摘要:Stiffened panel is widely used in ship construction. The research on its anti-blast performance is helpful to enhance the vitality of ship. In this paper, the stiffened panel is taken as the research object, and the blast test is carried out to study the blast response of the stiffened panel under the continuous plane shock wave load. According to the test results, the empirical expression of shock wave pressure with scale distance and load duration is proposed, and the numerical simulation is carried out by using the formula. It is found that the calculated results are in good agreement with the test results. The results show that the anti-blast performance of the structure is different in different directions under the action of stiffeners. Stiffeners can effectively improve the impact resistance of stiffened plates. In addition, the effect of peak pressure on the response of stiffened plate is discussed, and the ultimate load of stiffener is determined.
