摘要
船舶在水面行驶的过程中,如果水下发生爆炸,由此产生的冲击波会对船舶主体结构造成一定程度的损伤。远处的水下爆炸通常会造成船舶局部塑性变形,而接触式的水下爆炸,可能会使船体断裂,这是导致船舶水上倾覆的重要原因之一。为进一步明确接触式水下爆炸冲击波对船舶结构的毁伤情况,可以选择适宜的算法,通过数值模拟的方式,得到毁伤结果,为船舶抗冲击设计提供参考依据。
When a ship is traveling on the water surface,if an explosion occurs underwater,the resulting shock wave will cause a certain degree of damage to the main structure of the ship.The far-field underwater explosion usually causes local plastic deformation of the ship,while the contact-type underwater explosion may break the hull,which is one of the important reasons for the overturning of the ship.In order to further clarify the damage of the contact underwater explosion shock wave to the ship structure,an appropriate algorithm can be selected,and the damage results can be obtained by means of numerical simulation,which can provide a reference for the ship shock resistance design.This has important practical significance for improving the overall performance of the ship structure.
