对抛物面天线上的风力计算,主要是根据流体动力学理论和风洞模型试验数据进行的。国内外已对一些典型结构进行了分析和大量的风洞试验,得到了一些可以应用的数据,但风在抛物面形状物体上的分布是比较复杂的,是计算中其影响因素也比较多,在实际应用时,还需要进行综合判断和选用。其计算中遇到的主要问题可归纳为两大类:一是风速的确定;
Wind power calculations on parabolic antennas are based primarily on fluid dynamics theory and wind tunnel model test data. Some typical structures at home and abroad have been analyzed and a large number of wind tunnel tests have been carried out. Some applicable data have been obtained. However, the distribution of wind on paraboloid-shaped objects is quite complicated. There are also more influential factors in the calculation. Practical application, but also need to make a comprehensive assessment and selection. The main problems encountered in the calculation can be summarized into two categories: one is the determination of wind speed;
