摘要/Abstract

摘要： 随着通航船舶大型化的快速发展，对船闸浮式系船柱等通航设施提出了更高的要求。为保障船闸浮式系船柱结构在运行状态下的系缆安全，依托于某大型船闸工程项目，基于材料力学的基本理论推导得到了船舶系缆力与浮式系船柱柱身应变之间的定量关系，结合系缆力作用下浮式系船柱有限元模型的应变值计算结果，建立了船闸浮式系船柱的受荷响应力学模型。当浮式系船柱柱身同一截面位置指定测点处的应变已知时，便可基于该模型计算得出浮式系船柱所受系缆力，用以评估过闸船舶的系缆安全。通过将模型预测值与数值仿真计算结果进行对比分析，验证了模型的精度。研究成果可为实现船闸浮式系船柱在服役状态下的自动化感知预警及安全评估提供技术支撑。

Abstract: With the rapid development of large-scale navigation ships, higher requirements were put forward for navigation facilities such as floating bollard of ship lock. In order to ensure the mooring safety of the floating bollard structure of the ship lock in operation, the quantitative relationship between ship mooring force and floating bollard body strain was deduced, which was relied on a certain large-scale ship lock project and based on the basic theory of material mechanics. Combined with the calculation results of the strain value of the floating bollard finite element model under the action of the mooring force, the load-bearing response mechanical model of the ship lock floating bollard was established. When the strain at the measuring point at the same section of the floating bollard was known, the mooring force of the floating bollard can be calculated based on the proposed model, so as to evaluate the mooring safety of the ship passing through the lock. By comparing the predicted value of the proposed model with the calculation result of numerical simulation, the accuracy of the proposed model was verified. The research results can provide technical support for realizing automatic sensing warning and safety assessment of floating bollard of ship lock in service state.
