摘要
在哈尔滨工程大学船模拖曳水池中，研究了雷诺数在3．19×10^4～1．15×10^4的范围内，表面倾斜且前后不对称的筒形桅杆攻角从0°～180°，以15°为间隔，在均匀流场中所受的风载。分析了桅杆所受的周向压力、轴向压力和St随雷诺数和攻角的变化趋势。结果表明，倾斜壁面和攻角改变对压力分布和St有较大影响。
An experimental research of load acting on a cone-shaped mast in the even flow with high Reynolds number was done. The experiment was performed in the towing tank with the Reynolds number from 3.19 × 10^4 to 1. 15 × 10^6 and the attack angle between 0° and 180° in steps of 15°. The trend of pressure in the circumference and axis, St with Re and attack angle was analyzed. The results show that the inclined walls and the change of attack angle have great influence on the pressure distributing and St .
