摘要
针对大型船舶过闸期间系缆力难以实时量化监测的问题,通过对船闸浮式系船柱应变-系缆力受荷响应力学模型进行修正,采取实船试验对修正后的模型进行验证分析,统计过闸船舶系缆力实测历时曲线数据.结果表明:修正后的浮式系船柱受荷响应力学模型基本符合过闸船舶实测系缆力实时变化趋势,实测的船舶系缆力峰值与模型反演计算值之间的相对误差在±5%以内,修正后的力学模型能够准确地预测船闸浮式系船柱的受荷情况.研究结果可为船闸浮式系船柱数字化监测和工程化建设提供参考.
Abstract
To the problem of difficulty in real-time quantitative monitoring of mooring forces during the passage of large ships,the mechanical model of the strain-mooring force load response of the floating bollard of ship lock is modified.Real ship tests are conducted to verify and analyze the modified model,and the measured duration curve data of mooring forces of the passing ship are collected.The results show that the modified mechanical model for the load response of the floating bollard basically conforms to the real-time trend of measured mooring force of the ship passing through the lock.The relative error between the measured peak mooring force of the ship and the model inversion calculation value is within±5%.The modified mechanical model can accurately predict the load situation of the floating bollard of ship lock.The research results provide a reference for the digital monitoring and engineering construction of the floating bollard of ship lock.
