提出了内河双壳油船舷侧结构耐撞性能的简化分析方法,详细讨论了球鼻艏撞击作用下内河双壳油船舷侧结构的总体破坏模式及其渐进破坏过程.在考虑舷侧外壳板发生断裂破坏后的剩余抗撞能力的基础上,给出了双壳舷侧结构的撞击力―撞深曲线和吸收能量-撞深曲线,并与有限元仿真分析结果进行了比较.简化分析方法得到的结果与有限元分析基本上是一致的,这表明该方法能对内河双壳油船结构的耐撞性能做出合理预报,可用于这类油船耐撞性能的评估.

A new simplified analytical method is proposed to evaluate the crashworthiness of side structure of inland double-hull tankers. The failure modes and their progressive collapse behaviour of the side structure collided by a bulbous bow are described in detail. Considering the residual strength against the crashworthiness after the outer shell fracture,the curve of collision force versus penetration depth is plotted and compared to the FEM result. The comparison shows that the simplified analytical method is able to predict the structure damage of the double-hull in a reasonable manner, and thus can be used to evaluate the crashworthiness of the structure in ship design.
