舰船摇摆作用下综合集成桅杆强度实验

根据力学原理,采用倒置模型法对封闭式综合集成桅杆在舰船摇摆作用下的强度进行实验研究.比较其实验结果与数值计算结果发现,两者吻合较好.通过对大量工况下的应力测量结果分析,总结出了桅杆结构应力响应随舰船摇摆周期和幅值变化的规律.其结果可为新型桅杆的结构设计提供可靠的参考数据,并为舰船桅杆结构实验提供新的思路.

Strength Test of the Integrated Mast under Ship Sway

According to mechanical principle, experiments were conducted on the integrated mast, which is enclosed, to research on its stress under ship sway by using an inverted model method. The experimental results correspond with the numerical calculation results well. This paper summarized the variation of the stress response of mast’s structure with the period and amplitude of the ship sway by analyzing the measurement results in a large number of working conditions. The research aims to provide reliable reference data for the structure design of new style mast, and to provide a new idea for the structure experiment of the ship mast.
