关于客户
Laser Zentrum Nord (LZN) 和汉堡-哈尔堡技术大学 (TUHH) 是参与该研究项目的主要实体。 LZN成立于2009年，旨在支持从基础研究到工业应用的知识和技术转移。它与汉堡工业大学 (TUHH) 激光与系统技术研究所 (iLAS) 密切合作。该研究项目还得到了 BMBF（德国联邦教育和研究部）的资助。航空航天业供应商 Premium Aerotec (PAG) 是该项目的工业合作伙伴。
挑战
Laser Zentrum Nord (LZN) 和汉堡-哈尔堡技术大学 (TUHH) 正在寻求方法来改进采用激光增材制造方法制造的组件的设计和优化方法。面临的挑战是开发坚固而轻的结构，类似于骨骼等自然存在的生物结构。 TiLight 研究项目旨在将创新设计方法与新的制造能力相结合，利用高强度钛合金 TiAl6V4 材料经济地制造轻质部件。航空航天业是该项目的主要关注点，其中更轻的部件可以为飞机带来更高的负载能力或航程。飞机上的标准固定元件支架被选为该项目的测试对象。
解决方案
该解决方案涉及使用 Altair 的 HyperWorks、OptiStruct 和仿真驱动设计流程。考虑到 TiAl6V4 材料，开发了激光增材法的定制工艺链。优化工具 OptiStruct 用于创建基本的优化结构。然后对这些结构进行比较并使其适应自然界的生物示例，然后对最终几何形状进行最终数值验证。 HyperWorks Suite 用于组件设计的概念阶段，提供建模、分析、优化、可视化、报告和数据管理的集成解决方案。然后使用 CAD 工具对提议的设计进行细化，并使用 OptiStruct 对最终设计进行数值验证。

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.
Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
Case Study
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.
