关于客户
Ingeniacity SL 是一家西班牙工程服务提供商,为工程挑战提供创新解决方案并开发新的想法和方法。该公司通过提供“问题抽象”技术为各个行业提供服务,使其能够涵盖许多不同的应用程序。 Ingeniacity在结构设计和分析方面拥有丰富的经验,应用有限元分析(FEA)和计算流体动力学(CFD)技术,专门从事造船和汽车等行业的复合材料设计。
挑战
西班牙工程服务提供商 Ingeniacity SL 受 Juan Yacht Design 委托优化新型 Swan 50 级游艇的结构设计,特别关注设计由复合材料制成的新型船首斜桅。我们面临的挑战是创建一种结构,该结构能够提供尽可能高的刚度,同时又尽可能轻。船首斜桅是将前支索连接到船体的一根桅杆,是游艇结构的关键部分。由于需要考虑复合材料的特性以充分利用其轻量化和刚度潜力,船首斜桅的设计和优化提出了独特的挑战。由于船首斜桅的壁很薄,工程师还必须考虑屈曲模式,这对于保持较低的重量是必要的。这需要使用先进的计算机辅助工程 (CAE) 工具和优化技术,以有效处理所有必要的学科并及时提供准确的结果。
解决方案
为了应对这一挑战,Ingeniacity 转向 Altair 的 HyperWorks CAE 工具套件。该套件的工具可以简化所有材料的设计和优化过程,特别适合复合材料。使用的关键工具是 OptiStruct,它使设计师能够根据需要减轻和加强船首斜桅。 OptiStruct 采用三步方法:确定层下降和层堆积的最佳位置、开发层切割图案以及定义最佳堆叠顺序。工程师们遵循这种方法来设计复合材料制造的船首斜桅。用于此优化的负载工况在吊杆处具有 4500 N 的预紧力,同时来自钻机的重量超过五吨。借助 HyperWorks,工程师们能够创建新的船首斜桅设计,比之前的型号轻 34 公斤。

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.
