Eurocode3 1-6与DIN18800-4在风电机组塔架屈曲分析中的对比研究

摘要

At present, The theoretical calculation methods are widely used for buckling analysis of wind turbine tower . The European standards Eurocode3 1-6 and the German standards DIN18800-4 are two kinds of theoretical calculation methods commonly used,both of them have great guiding signifcance on the problem of anti-buckling in design of wind turbine tower, at the same time,they are analogous in calculation concept. In this paper, the parts of these two standards with related to anti-buckling design of wind turbine tower are compared and analysised, providing a reference for related research.%目前，针对风电机组塔架的屈曲分析一般采用工程算法，欧洲标准Eurocode31-6与德国标准DIN18800-4是两种十分常用的工程计算方法，两者对于塔架设计中的抗屈曲问题都有很强的指导意义，同时在计算思想上也有异曲同工之处。本文针对两部标准中与风电机组塔架屈曲设计相关的部分进行了比较与分析，为相关研究提供了一定的参考。
