【摘要】 本文对一般油轮在浅水不规则波浪中六自由度运动进行了试验分析 ,并对其碰底情况做了研究。试验时对有流情况下不同波高、不同装载的条件进行了分析比较。模型的六自由度运动是用非接触式六自由度运动测量与分析方法求得。该方法应用位置测量仪 (PSD)对安置在模型上的红外线发光源 (L ED)进行测量 ,然后用所编制的软件计算出模型的六个自由度运动情况。更多还原

【Abstract】 The 6D motions of an oil tanker model in shallow water with irregular waves have been measured and analyzed in the State Key Laboratory of Ocean Engineering at Shanghai Jiaotong University. Meanwhile, the occurrence of touching the basin bottom is observed and investigated. The performances of the model on various environmental conditions, such as significant wave heights and wave directions, current conditions, loading conditions and the conditions of the model with or without bilge keels, are tested and compared. A non contacted method for measuring and analyzing the 6D motions of the model is applied, and the position sensitive detector (PSD) is used to observe the movement of the light from the light emitting diodes (LED) which are fixed on the model. A computer procedure is developed for calculating the 6D motions of the model.更多还原
