摘要: 分析了船舶底部纵剖轮廓线的单点测量原理, 利用声波测量组件往复扫描, 测量多个吃水部位, 将船舶航速、扫描距离、扫描速度等数据进行有效处理, 提出了一种新的基于单波束声呐传感器的船舶底部纵剖轮廓线测量方法。以声波接收场的面积为约束条件, 给出了船舶底部边缘的判断判据, 推导了船舶底部轮廓线的重构公式, 并利用小比尺船模进行仿真试验。试验结果表明: 当船舶航速为2cm·s-1时, 测得19个轮廓点数据, 船艏、船艉吃水分别为2.91、3.09cm, 吃水差为0.18cm; 当船舶航速为4cm·s-1时, 测得10个轮廓点数据, 船艏、船尾吃水分别为2.79、3.15cm, 吃水差为0.36cm。所有测点一致性较好, 船舶航行姿态与实际相符。Abstract: The single-point measurement principle of buttock contour line at ship bottom was analyzed.Acoustic measurement components were used to measure several draught points through reciprocating scanning, various parameters including ship sailing speed, scanning distance and scanning speed were effectively processed, and a new measurement method of buttock contour line at ship bottom based on single-beam sonar sensor was proposed.The acoustic receiving area was taken as constraint condition, the judgement criterion of ship bottom edge was carried out, the reconstruction formula of buttock contour line at ship bottom was deduced, and simulation test was carried out by using small scaled ship model.Test result shows that when ship sailing speed is 2 cm·s-1, 19 contour points are measured, the draughts of ship bow and poop are 2.91 and 3.09 cm respectively, and the trim is 0.18 cm.When ship sailing speed is 4 cm·s-1, 10 contour points are measured, the draughts of ship bow and poop are 2.79 and 3.15 cm respectively, and the trim is 0.36 cm.All the measured point data are of good consistency, and the sailing attitude is consistent well with the actual state.
