摘　　要：针对研究浮体运动的海洋工程物理模型试验中风场的模拟要求,对两种实验室模拟实现技术方案进行了阐述和对比,发现了开敞方案在风场质量和经济性方面都要优于风洞方案并推荐使用。同时,采用变比尺船模风场系泊力试验方法,研究了模型的相似性、比尺效应和风速比尺等问题,得出了重力相似准则条件下风速比尺的修正系数。In the physical model experiment which studies the floating body in ocean engineering, two wind-filed simulation methods are discussed. The testing result shows that the open-style method is superior to the wind-tunnel method. Due to the reason of more satisfactory wind-filed quality and economical cost, the former method is recommended. Meanwhile, based on the experiment which adopts model vessels with different scales to test the mooring force in wind-filed, model similarity, scale effect, wind speed scale ratio and the like are studied, and the rational correction coefficient of wind speed in gravity similarity rules is eventually obtained.
