| 摘 要： | 浪向信息对船舶安全航行至关重要.然而实际海浪是复杂的三维不规则波,目前尚无简易的浪向预报装置,驾驶者只能靠目测初步判断浪向,同时根据船舶在波浪中的运动状态逐步调整航向.本文基于"二轴流速仪定向原理",将航行中的船舶纵摇、横摇运动信息转换为二轴流速仪的输出,实现了以最少的信息采集和数据处理方法以获得基本的浪向信息,为航行中的船舶提供了一较简易、可靠的浪向估计方法.

| Abstract: | It is very important to get wave direction information for ship safety guarantee. However, because of the complexity of 3D waves, therer are no simple and reliable instruments for predicting wave direction, and the captain can only estimate the wave direction by eyes, then adjust ship course in waves on basis of the ship motion characteristics. This paper presents a method to convert ship roll and pitch response to the outputs of two axis current meter with the oriented principle of two axis current meter. It provides a simple and reliable method of wave direction measurement for moving ship, which gets the wave direction information with the least cost of data collection and processing. |
