摘　　要：根据自航模试验结果,讨论了船舶在正随浪中航行时横甩的发生与波浪环境和航行状态的关系.在此基础上,利用约束模试验,测量了作用于随浪航行的船体上的波浪摇艏力矩,据此分析了船舶发生随浪横甩的原因.Free running model tests were carried out with a wire controlled model of 2.49 m in length.From this, it is clarifled that the occurrence of broaching-to phenomena in following seas is induced by a concerted action of the wave environment and ship's navigation, including the ratio of wave length to ship length, wave slope, ship's speed, etc.Moreover, measurements of the wave exciting yaw moment on a captive model traveling in following seas were conducted.It is identified that wave exciting yaw moment which exceeds the course-keeping ability of the rudder results in the occurrence of broaching-to phenomena.
