关于客户
波音公司是百年航空航天企业，是全球最大的军用飞机制造商。它以其对当前和新兴技术的理解和应用而闻名，以提高现有产品的功能并提供新的解决方案来满足不断变化的客户需求。波音公司的综合防御系统（IDS）业务部门负责旋翼飞机的设计和制造，这种飞机通过绕垂直轴旋转的机翼保持在空中。 IDS 部门不断致力于改进这些设计，以减轻重量并提高经济性、可靠性和制造效率。
挑战
波音公司的综合防御系统 (IDS) 业务部门是全球最大的军用飞机制造商，面临着改进旋翼飞机设计以减轻重量并提高可承受性、可靠性和制造效率的挑战。旋翼机（通过旋转机翼保持空中飞行的飞机）的设计是形式和功能的复杂平衡。主要目标是以最低的总重量提供最大的功能。重量影响旋翼的垂直升力能力，进而影响飞机的航程和在安全高度飞行的能力。然而，减轻重量也可以使飞机成为地面火力更容易生存的目标。此外，需要调整机身的刚度以减少振动，振动会影响乘客的耐力、武器的使用、机身的耐用性和机载电子设备的操作。这也是一个与体重有关的问题。节省的每一磅都是在效率、性能、防弹能力、士兵生存能力、维护和可修复性方面进一步提高的机会。
解决方案
波音公司求助于设计优化技术来应对这些挑战。他们使用 Altair OptiStruct 软件，通过为给定的设计空间、目标质量以及给定的目标和约束集的制造方法定义最佳材料分布来设计和优化机械结构的性能。该软件使工程师能够开发出稳健、高效的设计，与耗时的试错方法相比，这些设计在更短的时间内成功的可能性更高。例如，工程师利用 OptiStruct 拓扑优化技术，为波音 CH-47 Chinook 重型运输直升机的坡道制作了新型开放式桁架结构。新设计比原来的设计更坚固，同时重量减轻了 17%。开放式桁架结构还提高了坡道的弹道耐受性，因为新设计体积的减小比更密集的腹板和加强筋呈现出更稀疏的目标。

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.
