针对配置克令吊和绑扎桥的支线集装箱船,将绑扎桥和克令吊筒体结构整合设计成一体,缩减中间甲板宽度,克令吊筒体兼做绑扎桥中间位置的剪力板,在克令吊筒体围壁上开设通道,方便克令吊筒体前后堆箱通过内绑的形式连接克令吊柱体.采用有限元法计算分析绑扎工况和克令吊作业工况下结构强度和刚度,优化中间甲板和绑扎桥设计,验证结构设计的合理性.该整合式结构设计方案,既减小货舱长度,又能提高集装箱绑扎操作的便利性. 相似文献

Previously reported container losses were generally attributed to extremely violent motions of containerships due to adverse weather conditions. However, most existing specifications or standards adopted for containers and lashing equipment meet the requirement of static conditions. Hence, further researches on safer container shipping under heavy sea states are required. Consequently, an experimental study method is proposed to measure the dynamic response of 1/10 scaled lashing bridge and container stack. The scaled model of the lashing bridge is constructed based on the similarity theory. Based on two dimensionless numbers, Froude's number and Cauchy's number, eleven container scaled models are employed. A series of experiments with controlled parameters are performed using a three-degrees shaking table (roll, pitch, heave) to present sufficient data to verify the effectiveness of the numerical model. The results of experiments, numerical simulations and calculations of the VERISTAR procedure (developed according to the BV rule) are compared. This study aimed to explore the mechanical behavior of the lashing bridge and container stack under predetermined driving excitations (roll and pitch) which simulated heavy sea states. According to the results, the model can predict conditions similar to real situations of the lashing bridge and container stacks while storages on the weather deck. 相似文献
