关于客户
泰雷兹阿莱尼亚宇航公司是欧洲领先的航空航天制造商,在法国、意大利、西班牙、比利时、英国、德国和波兰开展业务。该公司为国防、地球观测、通信、导航和安全市场设计、集成、测试、运营和提供空间系统。泰雷兹阿莱尼亚航天公司在全球拥有约 7,500 名员工,处于航空航天业增材制造开发、实施和工业化的前沿。公司不断探索新技术和制造工艺,以改进其产品和服务。
挑战
欧洲航空航天制造商 Thales Alenia Space 热衷于探索增材制造 (AM) 在其空间卫星开发项目中的潜力。该公司希望研究增材制造与设计优化技术相结合的减重潜力。面临的挑战是找到一种将这些技术与新制造技术结合使用的方法。泰雷兹阿莱尼亚宇航公司选择卫星的铝制过滤器支架作为该研究的测试用例。该支架需要其支撑部件的结构载荷、通过过滤器的气流的热载荷以及太空旅行的极端温度的独特组合。该研究的主要目标是使用设计优化技术来降低支架的热合规性,同时优化组件的重量并为增材制造工艺的最终设计做好准备。
解决方案
Thales Alenia Space 与 Altair ProductDesign 合作,是因为 Altair 在开发设计优化技术并将其应用于航空航天业方面拥有专业知识。 Altair ProductDesign 的第一步是将支架的现有模型转换为可与 HyperWorks 的 OptiStruct 结构分析求解器一起使用的格式,并将两个模型组合在一起以创建独特的热结构模型。这使得可以并行探索两组约束的影响。一旦确认新模型能够准确代表物理支架,团队就进入设计优化阶段。使用 OptiStruct,该团队建立了模型并指定了该技术必须遵守的众多约束条件,以便提供令人满意的解决方案。支架被分为“可设计”和“不可设计”空间部分。 OptiStruct 使用拓扑优化技术提出了一种新的材料高效设计,该设计满足性能标准,同时去除对设计没有积极影响的区域的材料。然后将建议的几何形状解释为更适合增材制造工艺的布局,并转换为可制造的 CAD 模型。

Case Study
Airbus Soars with Wearable Technology
Building an Airbus aircraft involves complex manufacturing processes consisting of thousands of moving parts. Speed and accuracy are critical to business and competitive advantage. Improvements in both would have high impact on Airbus’ bottom line. Airbus wanted to help operators reduce the complexity of assembling cabin seats and decrease the time required to complete this task.
Case Study
Aircraft Predictive Maintenance and Workflow Optimization
First, aircraft manufacturer have trouble monitoring the health of aircraft systems with health prognostics and deliver predictive maintenance insights. Second, aircraft manufacturer wants a solution that can provide an in-context advisory and align job assignments to match technician experience and expertise.

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.

Developing Smart Tools for the Airbus Factory
Manufacturing and assembly of aircraft, which involves tens of thousands of steps that must be followed by the operators, and a single mistake in the process could cost hundreds of thousands of dollars to fix, makes the room for error very small.

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.
