挑战
诺斯罗普·格鲁曼系统公司 (NGSC) 是航空航天和国防技术领域的全球领导者,其后处理工作流程面临着重大挑战。该过程涉及根据 NASTRAN 结果手动计算组合应力,由于某些系统级模型中存在数百个具有不同横截面的一维梁单元,该过程特别耗时。每种类型的一维梁都需要自己的一组计算。面临的挑战是自动化该工作流程以节省时间,通过简单的用户输入最大限度地减少错误,并扩展流程以允许对各种模型(例如不同的横截面)进行后处理。
关于客户
诺斯罗普·格鲁曼系统公司 (NGSC) 是一家美国跨国公司,是航空航天和国防创新和技术领域的全球领导者。该公司的海洋系统部门位于加利福尼亚州桑尼维尔,是先进海军系统设计、开发和生产的领导者。 NGSC 以其对技术创新的承诺以及对航空航天和国防领域的重大贡献而闻名。
解决方案
Altair 和 NGSC 工程师合作应对这一挑战,首先讨论当前的工作流程、识别痛点并共享必要的材料,例如方程、示例 NASTRAN 模型和结果。 Altair Compose 之所以被选为解决方案,是因为其拥有针对 Altair HyperView 和 Altair HyperGraph 开发的丰富的 FEA 结果读取器库,并且社区对开放矩阵语言非常熟悉。我们向 NGSC 团队提供了一个“模板”脚本,该脚本读取模型和结果文件,根据提供的工程方程修改数据,并输出可在 HyperView 中可视化的自定义结果文件。通过进一步合作,NGSC 工程师能够修改、扩展脚本并将其应用到生产级后处理中。

Aerospace & Defense Case Study Airbus
For the development of its new wide-body aircraft, Airbus needed to ensure quality and consistency across all internal and external stakeholders. Airbus had many challenges including a very aggressive development schedule and the need to ramp up production quickly to satisfy their delivery commitments. The lack of communication extended design time and introduced errors that drove up costs.

Accelerate Production for Spirit AeroSystems
The manufacture and assembly of massive fuselage assemblies and other large structures generates a river of data. In fact, the bill of materials for a single fuselage alone can be millions of rows of data. In-house production processes and testing, as well as other manufacturers and customers created data flows that overwhelmed previous processes and information systems. Spirit’s customer base had grown substantially since their 2005 divestiture from Boeing, resulting in a $41 billion backlog of orders to fill. To address this backlog, meet increased customer demands and minimize additional capital investment, the company needed a way to improve throughput in the existing operational footprint. Spirit had a requirement from customers to increase fuselage production by 30%. To accomplish this goal, Spirit needed real-time information on its value chain and workflow. However, the two terabytes of data being pulled from their SAP ECC was unmanageable and overloaded their business warehouse. It had become time-consuming and difficult to pull aggregate data, disaggregate it for the needed information and then reassemble to create a report. During the 6-8 hours it took to build a report, another work shift (they run three per day) would have already taken place, thus the report content was out-of-date before it was ever delivered. As a result, supervisors often had to rely on manual efforts to provide charts, reports and analysis.
