2 soft platform with RNG k-ε sturbulence mode,considering the varying of wind attack angle every 15°,mean wind pressure coefficients of a cat-head-shaped pipe transmission tower for different wind attack angles were obtained by numerical simulation.
2软件平台,利用RNGk-ε湍流模型,对猫头形钢管塔的平均风荷载进行数值模拟,考虑风向角的变化,每隔15°模拟一次,得到了输电塔各风向角的平均风压系数,并进行了分析。
4) wind pressure asymmetric coefficient
风压不均匀系数
1.
Furthermore,most of the design parameters about windage yaw abroad,such as the conversion factor of the wind speed with height,wind pressure asymmetric coefficient and micro-effects of terrain,are stricter than those at home.
此外,国外在风速高度换算系数、风压不均匀系数和微地形影响等参数选取偏严,这可能是造成国内输电线路抵御强风能力不足的重要原因之一。
5) vrms
电压均方根,均方根电压
6) rms voltage

均方根 有时也称方均根。英语写为:root mean square(rms).
将n个项的平方和处以n后开平方的结果,即方均根的结果。
