关于客户
Aeroswift 是由南非航空制造解决方案提供商 Aerosud 和南非科学与工业研究委员会 (CSIR) 发起的项目。该项目于2011年启动，旨在释放不断增长的增材制造（AM）行业的潜力，提高市场竞争力，并为南非在金属增材制造领域提供独特的竞争优势。 Aeroswift 以其新一代金属增材制造 (AM) 系统而闻名，其构建体积比以往任何时候都更大。 Aeroswift打印机能够用多种金属建造大型3D打印金属飞机部件，其中包括钛合金，钛合金因其高性能和低重量的结合而在业界得到广泛应用。
挑战
南非航空制造解决方案提供商 Aerosud 和南非科学与工业研究委员会 (CSIR) 于 2011 年启动了一项具有挑战性的 3D 打印项目 Aeroswift。该项目旨在释放不断增长的增材制造 (AM) 行业的潜力，提高市场竞争力，为南非金属增材制造提供独特的竞争优势。面临的挑战是在 Aeroswift 打印机上构建大型金属无人机 (UAV) 框架，同时提高买飞比并减少开发时间和浪费。 Aeroswift 系统能够打印比以往更大的零件，并且速度比任何其他商用激光熔化机快十倍。然而，为了充分利用其能力，Aeroswift 需要一种设计大型增材制造产品的方法。
解决方案
Aeroswift 与 Altair 合作开发了一种设计大型增材制造产品的方法。他们使用 Altair Inspire，该软件使工程师能够设计大型无人机框架，并在 Aeroswift 机器上进行制造。设计过程包括无人机飞行要求规范、电子元件和传动系统选择、采用拓扑优化技术的机械设计、美观改进和可制造性改进。工程师通过增加分支大小运行第一步优化来分阶段实施拓扑优化方法，以降低查找主要负载路径的计算复杂性。该过程产生了包含最佳设计的厚度边界。然后，Aeroswift 团队重新创建了最终的几何形状，并使用更细的分支进行了第二阶段拓扑优化。这个过程将非常基本的设计转变为适合金属增材制造的拓扑优化设计。
