摘要： 基于现场实测和数值模拟,开展隔离开关与支架体系的动力风振实测与响应分析。基于计算流体动力学(computational fluid dynamics, CFD)模拟,研究隔离开关与支架体系的体型系数,并与规范计算结果进行对比分析;基于隔离开关与支架体系风振响应分析,开展风振系数数值模拟值与规范建议值的对比研究。研究结果表明:基于规范计算的格构式支架体型系数明显偏大,规范计算的体型系数相对保守;动侧结构的平均振动水平高于静侧结构,触头端部和结构顶部的位移响应明显高于支架顶部;设备支架在不同风攻角下的风振系数存在明显差异,其中60°风攻角下最大,对于斜风向角工况下规范给出的建议风振系数偏小。本研究结果可以为隔离开关与支架体系抗风设计提供科学依据。
