船舶在风浪中航行时保向问题的探讨

本文在建立船舶在风浪中的低频操纵运动方程式的基础上，探讨了船舶在风浪中的舵力保向问题。从工程实用的角度，提出了一个船舶在风浪中航行时保向舵角的近似计算公式。以“育英轮”为例，进行了计算。从保向的角度，提出了船舶在大风浪中航行时，提高抗风浪能力方法和安全航行的措施，并可望对实际工作有一点指导意义。

Study on Course-Keeping Performace during Ship Sailing in Wind Wave

Based on low frequency ship manoeuvring equation including wind wave force,that was presented by this paper,course-keeping performace by rudder force during ship sailing in wind wave was discussed. From the view point of engineering,a formula of estimating rudder angles for course-keeping was presented. In order to keep the course,a method for enhancing ship ability against wind wave,and a scheme for safe navigation,were proposed when ships sailing in wind wave.
