摘要
本文以自卸式散货船的84m自卸臂为研究对象,进行了高雷诺数下回转风力矩的规范计算与数值计算,比较研究了两种计算方法下的风载荷系数对回转风力矩的影响,结果表明:数值计算下的风力矩值小于规范计算下的风力矩值。
Taking the boom of a certain self-unloading bulk carrier as a case of study, this paper uses rules calculation method and numerical simulation method to calculation wind load in case of the large Reynolds number. A comparative study is made between the two methods, and result shows that the wind drag torque by numerical simulating is smaller than the one by rules calculating.
