摘要
阐述了3MW铸造前机架的几何拓扑优化设计方法,基于TOSCA软件对机架结构进行拓扑优化,得到机架的材料分布情况,并确定几何重构模型;然后在应力分析的前提下,对机架结构进行形状优化,解决拓扑机架出现的局部应力集中,从而细化模型的构型和基本尺寸;最后通过Sculptor变形控制和Isight优化平台集成ANAYS有限元分析软件对机架进行参数化优化,在保证结构性能稳健性的前提下得到更好的轻量化的机架模型。
A topology geometry design method of 3 MW wind turbine mainframe is introduced.The material distribution of mainframe is obtained on the basis of topological optimization by TOSCA software,and the model is rebuilt.On the premise of strain analysis,the shape optimization of mainframe is carried out to solve the stress concentration of the topological frame,so as to refine the configuration and basic dimensions of the model.Finally,by parametric optimization based on Sculptor deformation control and Isight optimization platform integrated finite element analysis software ANSYS,a lightweight mainframe is designed which has well structural performance.
