摘要

为探究风电行业内塔筒屈曲现象频发的原因

以风电塔筒屈曲计算最常用的欧洲EC3壳结构规范为研究对象

分析新、旧两本规范对于屈曲承载力计算方法的异同。针对两本规范计算方法中的制造质量、屈曲折减系数等关键参数开展了定量分析。经研究发现

新、旧EC3壳结构规范中经向屈曲承载力计算公式差异较大

制造质量对风电塔筒屈曲承载力影响较大

尤其是当采用新版规范进行塔筒设计时

应谨慎选择制造质量参数的取值。

Abstract

To explore the reasons for frequent tower cylinder buckling phenomena in the wind power industry

this article takes the European EC3 shell structure code

which is the most commonly used calculation method for tower buckling

as the research object. It analyzes the similarities and differences between the new and old versions of this code in terms of their methodologies for calculating buckling capacity. A quantitative analysis is conducted on key parameters such as manufacturing quality and buckling reduction factors used in the calculation methods outlined in both codes. The study reveals significant differences in the formulas for calculating the meridional buckling capacity between the new and old EC3 Shell Structures Codes. Furthermore

it highlights that manufacturing quality has a substantial impact on the buckling capacity of wind turbine towers. Notably

when designing towers using the new version of the code

careful consideration should be given to the selection of manufacturing quality parameters to ensure accurate and reliable buckling capacity calculations.
