挑战
阿尔斯通是综合铁路系统领域的全球领导者，面临着优化现有部件设计的挑战，以通过铸造或增材制造技术进行制造。受影响的部件是阿尔斯通 Metropolis 装置中用于支持防滚系统的火车转向架部件。人们发现该零件的初始设计对于其所承受的工作负载而言过于坚固，而且安全系数也有点太高了。阿尔斯通工程师的任务是改进现有铸件的设计，特别是优化其金属增材制造的生产。面临的挑战是改进整体设计，同时优化材料使用，并探索增材制造的新生产方案。
关于客户
阿尔斯通是可持续交通的推动者，为铁路行业开发和营销系统、设备和服务。该公司管理市场上广泛的解决方案，从高速列车到地铁和有轨电车，以及维护和现代化、基础设施和信号解决方案等定制服务。阿尔斯通的业务遍及 60 多个国家，拥有员工 31,000 名。该公司不断追求最佳的制造和开发流程，以创造最好的产品。对于这个特定项目，阿尔斯通的工程师的任务是改进其 Metropolis 装置中使用的现有铸件的设计。
解决方案
阿尔斯通采用了仿真驱动的设计方法，使用solidThinking Inspire 进行拓扑优化，使用solidThinking Evolve 进行形状细化。第一步涉及使用 SolidThinking Inspire 进行分析，这证实了早期使用 Altair HyperWorks 进行的有限元 (FE) 分析的结果。为了改进设计并优化材料使用，增加了零件的设计体积，然后进行了拓扑优化。经过 Inspire 的多次迭代，找到了定制的解决方案，然后使用 SolidThinking Evolve 完善了外部形状。然后通过详细的有限元分析再次验证最终的几何形状。阿尔斯通还与当地 3D 打印公司合作，准备和分析增材制造零件。使用solidThinking Inspire、solidThinking Evolve 和Altair HyperWorks 解决方案使工程师能够完成流程并支持结构测试。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
