传统的风力涡轮机叶片制造依赖于大型、昂贵的模具。相反，使用增材制造来打印叶片的内部结构，在其上可以铺设复合材料层片，可以显著降低制造成本，并且可以“3D打印”拓扑优化设计，提高结构效率。一般来说，拓扑优化与增材制造集成良好。然而，存在与在风力叶片设计中采用拓扑优化相关联的两个主要挑战，即考虑：（i）叶片的气动弹性响应;以及（ii）在复合层压材料以及印刷结构中将采用的各种不同材料。为了应对这些挑战，本文提出了一个新的多步骤的设计和优化框架依赖于三个软件的组合。首先，传统的气动伺服弹性模型用于评估叶片的载荷和位移。然后，使用拓扑优化软件对叶片层压板和核心结构进行优化。第三，使用网格生成器将拓扑优化的”灰色”设计转换为可以使用增材制造来打印的等效蜂窝设计。本文介绍了这种设计框架的完整方法和初步的概念验证拓扑优化解决方案。
Conventional wind turbine blade manufacture relies on large, expensive moulds. Instead, using additive manufacturing to print the internal structure of blades, upon which it would be possible to lay composite plies, could significantly reduce manufacturing costs and, as one could" 3D print" topologically optimal designs, improve structural efficiency. In general, topology optimisation integrates well with additive manufacturing. There are, however, two main challenges associated with the adoption of topology optimisation in wind blade design, ie accounting for:(i) the aeroelastic response of blades; and (ii) the variety of different materials that would be employed, in the composite laminates as well as the printed structure. To address these challenges, the present paper proposes a new multi-step design and optimisation framework relying on the combination of three software. First, a conventional aero-servo-elastic model is used to evaluate blade loads and displacements. Next, a topology optimisation software is used to optimise the blade laminates and core structure. Third, a lattice generator is used to convert the topological optimised" grey" design into an equivalent cellular design that can be printed using additive manufacturing. The full methodology of this design framework and an initial proof-of-concept topology optimisation solution are presented in this paper.
