摘要
[目的]随着风电进入平价时代,风机基础钢筋的设计优化具有十分重要的意义。[方法]以具体的工程实例为背景,采用CFD风机基础设计软件进行结构设计,得到了风机基础的混凝土和钢筋工程量。然后,采用ABAQUS有限元软件建立了风机基础的有限元模型。[结果]分析表明,底板底面径向钢筋的内侧端部位置、底板底面内圈环向钢筋的应力较大。通过分析计算,指出了传统的设计方法在配筋计算中存在的问题,总结出了优化配筋的建议,并与原方案的配筋结果进行了对比。[结论]结果表明,基础底板底面径向钢筋和底板底面环向钢筋的优化幅度均在10%以上。该结论可用于指导工程设计人员开展设计优化。
[Introduction]With wind power entering the era of parity,the design optimization of fan foundation reinforcement is of great significance.[Method]In a practical engineering case,the CFD foundation design software was used for structural design.Then,the finite element model of wind turbine foundation was established by ABAQUS software.[Result]The analysis shows that,the position of the inner end of the radial reinforcement and the inner ring of the circumferential reinforcement are the positions of the maximum stress in the reinforcement system.Through analysis,the problems existing in the reinforcement calculation of traditional design method are found.Reinforcement optimization is summarized and compared with the original reinforcement scheme.[Conclusion]The optimization range of radial reinforcement and circumferential reinforcement is more than 10%.These conclusions can be used to guide engineers for design optimization.
