【摘要】 本文介绍了椭圆形高杆灯在小量级风洞中 ,用 1 :8缩比模型进行实验研究的方法 ,主要测出了灯及灯盘在各向风的作用下所受的气动力的变化规律 ,并对此进行了简单分析 ,找出了灯及灯盘所受最大气动力的相对位置及体型系数 ,为该灯的强度校核提供了可靠的气动力数据。更多还原

【Abstract】 Presents an experimental method to simulate a pole sustained elliptic lamp in a low speed wind tunnel with a scale of 1:8 The laws of change of forces acting on the lamp and its fitting from winds at various directions are surveyed and analysed The relative position of the maximum force and the structural factors are found It provides aerodynamic data for the strength evaluation of similar lamps and fittings更多还原
