摘　　要：船舶在海上航行时,存在与其他船舶发生主动或被动碰撞的风险。为准确评估船舶的耐撞性能,以某船为例,考虑多种计算工况,对目标船的耐撞性能进行动态响应计算,获得机舱及艏部区域的结构损伤、应力、能量吸收等动态结构响应,并计算获得被撞船达到临界状态时的极限撞击速度。研究成果可为船舶的防撞结构设计提供参考。When ships are sailing on the sea, there is a risk of active or passive collision with other ships. In order to accurately evaluate the crashworthiness of the ship, taking a ship as an example with consideration of a variety of calculation conditions, the dynamic response of the target ship’s crashworthiness is calculated. The dynamic structural response of the structure damage, stress and energy absorption of engine room and bow area is obtained. The ultimate impact velocity is calculated when the collision ship reaches the critical state. The research results can provide reference for the design of anti-collision structures for ships.
