摘要
集装箱船在规定的运营工况和环境条件下运行时,不论是处于完整状态还是破损状态,都需满足安全和环境友好的要求,因此有效评估破损之后的船体结构,确保船舶安全运行较为重要。采用舱段有限元法,通过对比不同破损状态下的结构应力响应评估主要构件的屈服和屈曲强度,最终确定破损工况评估方法。研究结果表明,该方法合理,有助于保证集装箱船的结构安全和开展优化设计。
Container ships,no matter intact or damaged,must satisfy the safety and environmental requirements when operating under the prescribed operational and environmental conditions.Therefore,the effective assessment of the damaged hull structures is important to ensure ship's safety.Using the finite element method for hull section,the yielding and buckling strength of the primary structures are evaluated by comparing the stress response of the structures under different damaged states to establish the evaluation method for damage condition.The research results show that the method is reasonable and conductive to structural safety and optimization design of container ships.
