中文摘要:
      为便于在动员民船上快速加装,某型直升机机库采用集装箱拼装结构。针对恶劣海况下机库的整体稳定性和安全性问题,研究通过采用绑扎的方式进行加强。本文首先分析了组成机库的单个集装箱、机库侧壁等组件在非绑扎和绑扎状态下的受力与变形;然后输入恶劣海况下的极端工况数据进行计算,结果显示机库部件受力和变形将对机库安全造成不利影响,应进行绑扎加强;最后通过绑扎后机库整体稳定性和抗侧力计算,结果显示机库整体和侧壁的受力可完全被绑扎杆拉力抵消,绑扎加强能够提高机库的安全性。
英文摘要:
      A helicopter hangar adopts assembled structures based on containers for quick installation activity on board. Aiming at the problem of overall stability and safety of hangar under severe sea conditions, this paper studies how to reinforce the hangar by lashing. Firstly, analyzed the force and deformation of the hangar components under non lashing and lashing states. Then, input the data of extreme working states under severe sea conditions for calculation, the results show that the deformation of hangar components can cause adverse effects on hangar safety, and it is necessary to reinforce the hangar . Finally, calculated the overall stability and resistant lateral force of the hangar after lashing reinforcement, the results show that the forces on the whole hangar and the side wall can be completely offset by the tension of the lashing rod, and the lashing reinforcement can improve the safety of the hangar.
