ESA selects Siemens and Sonaca to develop aerospace design applications for metal additive manufacturing

欧洲航天局（ESA）选择了西门子数字工业软件来开发用于金属添加剂制造的航空航天设计应用。这些应用程序将使用西门子的端到端软件进行工业添加剂制造，该软件结合了生成工程，拓扑优化，预测分析，过程仿真，构建准备和生产执行。

The two-year long project, named Design4AM, will be a collaboration between Siemens and Sonaca, a specialist in aerospace structures, with financial support from ESA and the Belgian Federal Science Policy Office (Belspo). The goal of the Design4AM project is to deliver a validated process for using Siemens’ additive manufacturing software to design and produce optimized, light-weighted structural parts for space applications, such as fittings (structurally bonded to CFRP panel), supports, and bipods.

重量是空间应用特别关键的问题；根据行业报告，一磅有效载荷等于10,000美元的发射成本。增材制造技术可用于轻巧的发射器，推进器，卫星和各种航天器组件中的任何复杂结构。

西门子NX软件和Simcenter软件支持engineers to explore a range of design concepts in an automated closed-loop process that takes into consideration engineering performance, manufacturing process and operation cost requirements. These tools can account for manufacturing constraints such as thermo-mechanical part distortion, the structural part orientation in the building chamber or the design of supporting structures. The integrated software environment can shorten the part conceptual design and optimization process, helping enable higher performance structures to be manufactured.

“Additive manufacturing can help ESA reshape everything for optimal performance at reduced cost, in comparison to traditional manufacturing methods that require multiple steps, tools, and treatments to achieve the desired outcome,” said Didier Granville, RTD projects Manager for Siemens in Liège. “Working with Sonaca, we will be able to help ESA take advantage of additive manufacturing to deliver high-performance structures capable of withstanding the extreme forces that occur during space satellite launches.”
