【摘要】：载人潜水器作为海洋探测以及资源开发利用的重要装备,各国竞相投入了大量的人力物力进行研制建造。载人潜水器由于自身重量以及尺寸限制,其自持力以及续航力都不大,一般需要母船的运载以及支持,因此在海上作业时,需要将潜器从母船上吊入水中,而当其完成预定工作任务或者出现故障需要返航时,又需要将其回收到支持母船上进行保养和维修。吊放回收作业时母船与潜水器之间距离较小,且在波浪作用下二者时刻处于运动状态,就使吊放回收潜水器成为一项非常复杂和危险工作,潜水器吊放回收系统性能的好坏直接决定了潜水器的性能发挥以及使用安全。依据设计规范要求,参考现有潜水器吊放回收系统结构及功能特点,针对深水轻载作业型载人潜水器和潜水器母船的结构尺度及性能,进行了载人潜水器吊放回收系统的结构设计以及操作流程设计工作。结构设计主要包括吊放回收系统主尺度确定以及各部件的性能规格确定,并完成了吊放回收系统三维模型的构建。操作流程设计包括吊放作业以及回收作业流程设计,进一步明确了操作过程中吊放回收系统各部件的工作原理以及操作方式。在完成吊放回收系统结构设计的基础上,文章完成了母船吊放回收潜水器模型试验的设计,实施以及试验数据的处理工作,依据试验得到的母船模型在波浪中的运动响应求出了母船尾部吊点运动响应参数,并对悬挂潜水器时吊缆拉力以及潜水器运动响应进行了测量以及分析,同时还对悬挂潜水器后母船在波浪中运动响应的变化进行了研究。最后对母船尾部悬挂潜水器时潜水器的运动及受力进行了分析,并通过Simulink软件进行了动力学仿真,得到了在不同波浪圆频率下母船吊放潜水器时吊缆摆角θ和吊缆拉力波动幅值△T。并对波浪圆频率ω、水平加速度幅值Ax、竖直加速度幅值Az、水平与竖直加速度的相位差δ以及吊缆长度l对吊缆摆角θ和吊缆拉力波动幅值△T的影响进行了一系列仿真分析。
[Abstract]:As an important equipment for ocean exploration and resource development, many countries have invested a lot of manpower and material resources in the development and construction of manned submersible. Because of their own weight and size constraints, the manned submersible has little self-sustaining capacity and endurance, and generally requires the carriage and support of the mother ship, and therefore, when operating at sea, it is necessary to lift the submersible from the mother ship into the water, When they complete their scheduled work or need to return to the ship if they fail, they need to be recovered to support the mother ship for maintenance and repair. Because the distance between the mother ship and the submersible is small and they are in motion at all times under the action of waves, the lifting and recovery of the submersible becomes a very complicated and dangerous task. The performance of submersible hoisting and recovery system directly determines the performance and safety of the submersible. According to the requirements of the design code and referring to the structure and functional characteristics of the existing submersible hoisting and recovery system, the structural scale and performance of the deep water light duty type manned submersible and the submersible master ship are discussed. The structure design and operation flow design of hoisting and recovery system for manned submersible are carried out. The structure design mainly includes the determination of the main scale of the hoisting and reclaiming system and the determination of the performance specifications of each component, and the construction of the three-dimensional model of the hoisting and reclaiming system is completed. The operation flow design includes hoisting and reclaiming operation flow design. The working principle and operation mode of each part of the hoisting and reclaiming system in the operation process are further clarified. On the basis of the structure design of the hoisting and reclaiming system, the design, implementation and data processing of the model test for the hoisting and recovery submersible of the mother ship are completed in this paper. Based on the motional response of the mother ship model in the wave, the parameters of the motional response of the hoisting point at the rear end of the mother ship are obtained, and the cable pulling force and the motion response of the submersible are measured and analyzed. At the same time, the change of the response of the mother ship in the wave is studied. Finally, the motion and force of the submersible when the mother ship is suspended at the rear end are analyzed, and the dynamic simulation is carried out by Simulink software. The hoisting angle 胃 and the fluctuation amplitude of cable tension are obtained when the mother ship hoists the submersible at different wave circular frequencies. The effects of wave circular frequency 蠅, horizontal acceleration amplitude Ax, vertical acceleration amplitude Az, horizontal and vertical acceleration phase difference 未 and cable length l on cable swing angle 胃 and cable tension fluctuation amplitude T are analyzed.
