摘要
利用OrcaFlex软件建立起重船及其起吊系统非线性的三维运动模型,基于凝集质量法和时域非线性响应分析求解起吊系统受波流作用时在吊放各阶段的摆振规律,研究了波浪周期和波高对系统吊放阶段面内摆角及有效张力的影响。所得结论对海洋工程机械的吊放控制及预测有一定的参考价值。
The three-dimensional motion model of the crane ship and its lifting system was established by Orca Flex.Based on the lumped-mass method and the time-domain nonlinear response analysis,the vibration law of the lifting system under the action of wave and current was studied.The influence of wave periods and heights on in-plane swing angle and effective tension at dropping stage were studied.The conclusions are of some reference value for the lifting control and forecasting of marine engineering machinery.
