关于客户
Amazone 是一家开发和生产高品质创新农业技术的公司，致力于实现和支持现代经济的耕作方法。他们致力于利用先进的开发工具、流程和制造方法为客户的成功做出贡献。他们的产品在非常恶劣和变化极大的条件下使用，他们明白除了服务质量和备件的可用性之外，产品的使用寿命也是农民购买的一个关键标准。因此，在开发新产品时，他们不仅必须在价格上具有竞争力，还必须考虑产品的耐用性，因为这会影响制造商在市场上的声誉。
挑战
Amazone 是一家创新农业技术生产商，面临着将焊接悬架部件重新设计为铸造部件的挑战，同时提高其重量和耐用性。相关部件是用于土壤耕作的牵引式光盘耙 Catros-2TS 的一部分。原始部件是一个重 245 kg 的复杂焊接部件，连接单个部件需要 16.5 m 的焊缝。这使得生产过程既耗时又昂贵。挑战不仅在于优化制造工艺，还在于提高组件的使用寿命，因为产品使用寿命是农民的一个关键购买标准。设备必须足够坚固，能够适应恶劣的操作条件，并且设计改进不得导致最终产品的价格上涨。
解决方案
Amazone 采用模拟驱动的设计流程来消除不必要的设计迭代并更快地达到最终设计。他们使用了 Altair Engineering 的结构求解器和优化工具 OptiStruct 以及 SolidThinking Inspire。工程师首先评估了采用铸造工艺生产的部件的重量减轻和性能提高。他们进行了前期拓扑优化，并定义了可能的设计空间和边界条件，例如载荷、所需的刚度和制造限制。该软件计算需要多少材料以及必须将其放置在哪个位置才能满足结构强度等要求。根据优化结果，工程师创建了详细设计，然后使用 OptiStruct 进行有限元分析进行评估。铸造版本实现了更轻的重量和更平滑的结构过渡，从而减少了刚度变化。与原始组件焊缝中的载荷相比，新设计的铸造材料中的总体载荷显着降低。

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.
