摘要
以1艘船体纵向结构在船舯0.6倍船长范围内存在突变的内河汽车运输船为研究目标,根据规范要求,对目标船艉部机舱前端壁结构突变区域的强度进行评估,考虑目标船舷侧存在较大开口,且连接上层建筑甲板间的立柱较弱,上层建筑无法完全参与总纵强度的特点,对目标船舱段模型进行适当简化,提出计算端面修正弯矩的简单方法,计算分析目标船突变区域的结构强度。
An inland river vehicle carrier with abrupt change in its longitudinal structure within 0.6 L of the ship was taken as the research object. According to the requirements of the rule, the strength in the mutant region of the front wall at the target ship’s engine was assessed. Considering the characteristics that the superstructure will not fully participate in the overall longitudinal strength, due to the large openings on the side of the target ship and the weak columns connecting the decks of the superstructure, the model of target ship was appropriately simplified, and a simple method for calculating the end correction moment was proposed. The structural strength of target ship in mutant region was calculated and analyzed.
