针对风电塔筒极易发生屈曲破坏的问题,以筒形结构抗屈曲加劲肋设计为例,提出了一套集成化风电塔筒抗屈曲加劲肋设计方法。采用APDL语言进行建模和加载,自动提取屈曲计算结果作为参数,建立优化的状态变量和目标函数,采用零阶函数对数目众多且离散的变量进行优化,并可提供多组可行数据供用户比对分析。算例分析表明,该方法有效可行。 Aiming at the problem of buckling failure of wind tower, the design method of buckling stiffener of integrated wind tower is proposed by taking the design of buckling resistance of tubular structure as an example. Using APDL language to model and load, the buckling calculation results are extracted automatically as parameters, and the optimal state variables and objective functions are established. The zero-order function is used to optimize a large number of discrete variables and provide multiple sets of feasible data for user ratio Analysis. The example analysis shows that this method is effective and feasible.
