港口船舶系泊载荷参数化及特性研究

Research on the parameterization and characteristics of ship mooring in harbor

港口船舶系泊分析对码头结构、船舶本体安全至关重要,系泊缆力大多基于静态载荷理论人工计算,数值模拟与水池试验往往简化了环境约束,导致计算效率与精度偏低且成本较高。基于国内港口系泊载荷计算原理,通过风浪流实时动态监测数据输入,编程实现了动态环境因素下船舶系缆力的参数化计算。对比水池系泊试验结果表明,环境载荷程序参数化计算结果较试验结果偏差在5%以内,可用于实际工程载荷计算。

Mooring analysis is very important to the structure of wharf and the safety of ship in harbor.Mooring loads are usually calculated manually based on static theory.Numerical simulation and pool test simplify the constraints,which lead to low calculation efficiency and accuracy and high cost.The parameterized calculation of mooring is realized by inputting dynamic data of wind,wave and current based on domestic principle.The results show that the deviation between the calculation results of environmental load program and the test results is within 5%,this purpose can be used in the engineering.
