摘要

为丰富大跨度光伏柔性支架风振特性研究,以某三跨四排大跨柔性光伏支架为例,通过SAP2000有限元模拟的方式,对结构模态进行分析,并研究敏感性参数对结构风致振动影响,结果表明:模态以竖向振动为主,到第三节才出现扭转变形;承重索预应力对结构动力响应有着明显影响.随着承重索预应力的增大,位移风振系数、索力风振系数逐渐增大.基于以上分析,总结承重索预应力对大跨度光伏柔性支架风振响应的影响.

Abstract

In order to enrich the research on wind-induced vibration characteristics of long-span photovoltaic flexible bracket,a three-span four-row long-span photovoltaic bracket is taken as an example.With the increase of prestress,the wind vibration coefficients of displacement and cable force increase gradually,and the prestress mainly affects the de-flection of the structure.Based on above analysis,the influencing factors of the wind-induced vibration of the long-span photovoltaic flexible bracket are summarized.
