摘要
随着海运行业在国际贸易中所占的重要地位日益明显,船舶在海洋航行的过程中会受到风浪、撞击等问题影响,因此对船舶航行过程中的安全管理问题越来越受到关注。为保障船舶正常安全行驶,需要对船舶结构健康状态进行及时有效的检测,并对船舶运行状态进行综合评估。当前船舶健康状态综合评估方法存在较强的主观性与单一性,不能对船舶监控状态进行准确评估,难以及时发现船舶结构中存在的安全隐患。考虑到船舶评估的复杂性,提出基于光纤网络的船舶T形节点结构健康状态评估分析方法。结合光纤网络灵敏度高、抗干扰能力强等优点,设计了光纤传感器,以便及时准确的对船体各部受力变形情况进行检测和评估,使船舶健康状态综合评估的结果更为精准高效,并结合实验对该方法进行实验检测,实验结果证实该方法切实有效,具有较高的实用性和参考价值。
As the shipping industry plays an increasingly important role in international trade, ships will be affected by wind waves, impacts and other issues in the process of ocean navigation, so the safety management of ships in the process of navigation has been paid more and more attention. In order to ensure the normal and safe operation of the ship, it is necessary to carry out timely and effective detection of the health status of the ship structure, and to conduct a comprehensive assessment of the operation status of the ship. At present, there is a strong subjectivity and singleness in the method of comprehensive assessment of ship health status. it is not accurate enough to assess the ship monitoring status in time, and it is difficult to discover the potential safety hazard in the ship structure in time. Considering the complexity of ship evaluation, a method of health status evaluation and analysis of ship t-joint structure based on optical fiber network is proposed. Combined with the advantages of high sensitivity and strong anti-interference ability of optical fiber network, the optical fiber sensor was designed to detect and evaluate the stress and deformation of each part of the ship in time and accurately, so that the comprehensive evaluation result of ship health status was more accurate and efficient. the method was tested by experiments. the experimental results show that the method is effective and has higher practical and reference value.
