摘　　要：航行中船舶直观给出的传感器实测相对风,需结合航速航向等运用矢量运算法则才能计算出真风。本文通过定量分析风速风向传感器零位安装误差对真风解算的影响,建立了传感器风向分辨率与零位安装误差对真风解算的误差传递模型。研究结果表明,风速风向传感器的零位安装精度5°以内的风向分辨率对真风计算的结果影响不大,但叠加传感器的零位安装误差后,尤其是正向误差(安装误差在11°以上),在高航速高真风的情况下,能达到30%以上的误差。要提高真风解算的准确性,还须严格控制传感器的零位安装精度。The wind sensors installed on the ship＇s mast can measure the relative wind directly when voyaging. However,only by using the vector algorithm combined with the ship＇s speed and heading can we calculate the true wind. Through quantitative analysis of the influence of the wind sensor＇s zero installation error on true wind calculation,the error transfer model of the wind sensor＇s direction resolution and zero installation error was established in this paper. Analysis shows that the wind sensor＇s zero installation accuracy has important influence on the true wind calculating results,in some cases it can be up to an error of 30%. In order to improve the accuracy of the true wind calculating,we must strictly control the zero installation precision of the sensor.
