关于客户
本案例研究中的客户是 Nurmi Cylinders，这是一家芬兰制造商，生产用于近海、工业、船舶和移动液压系统的液压缸产品。 Nurmi Cylinders 是该项目的资助者之一，并提供了针对增材制造进行优化的阀块示例。该公司为阀块的设计提供了边界条件和额外的内部限制，包括必须放置阀门的位置以及必须考虑哪些加工公差。内部通道的尺寸、位置和方向也由 Nurmi Cylinders 选择，属于非设计空间的一部分。
挑战
VTT 是芬兰领先的研究和技术中心，与芬兰液压缸产品制造商 Nurmi Cylinders 合作，利用增材制造 (AM) 优化阀组，以满足要求严苛的工业应用。我们面临的挑战是设计一个能够充分受益于增材制造工艺的阀块，减小其尺寸和所需材料的数量，并优化其内部通道，为客户生产更好的组件。阀块的传统制造方法包括将金属块形成所需形状并钻内部通道以适应液压流体流动。这个过程通常很麻烦，并且容易出现对准问题和潜在的泄漏。此外，并非所有组件或产品都适合增材制造，具体取决于其尺寸、形状、设计和所需数量。
解决方案
VTT 工程师使用 Altair Engineering 的 HyperWorks® CAE 软件套件来设计、优化和分析阀块。套件中的优化工具和有限元求解器 OptiStruct® 用于根据客户提供的定义的设计空间、限制、载荷和其他边界条件提出最佳设计。然后使用 OptiStruct 的形状生成工具之一 OSSmooth 对优化后的设计进行重新网格划分和重新分析，以确保满足所有初始设计要求且不超过应力限制。为了准备用于打印的优化网格，VTT 使用了 Materialise 的一款名为 3-maticsSTL 的软件应用程序，该应用程序可以进行设计修改、重新网格划分以及创建 3D 纹理、轻量级模型和共形结构。阀块经历了多次设计迭代，改变了内部流体通道的路线以优化性能。最终设计是使用选择性激光熔化 (SLM) 机器打印的。

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.
