摘　　要：采用数值仿真手段,在各风向角下计算分析船舶甲板上6种不同的集装箱堆箱布置对船舶纵向风向力、横向风力和艏摇风力矩的影响。借助风洞设备对相应研究工况进行风洞试验验证,结果表明数值计算结果与试验结果吻合较好。为有效评估不同堆箱布置形式下航行集装箱船的风阻力,提出考虑遭遇风向角范围的"阻力系数面积RA"评估指标。The longitudinal,lateral and yaw wind forces on a container ship with 6 kinds of container stacking configurations at different wind angles are calculated and analyzed with numerical simulation method. Meanwhile,wind tunnel tests are conducted under the corresponding conditions for verification. Comparison show that the results from the two methods accord with each other. An index named as＂resistance coefficient area＂is introduced for effectively evaluating the wind resistance of navigating ship with different container configurations. The ＂resistance coefficient area＂varies according to the wind attack angle for given container stacking configuration.
