关于客户
本案例研究的客户是印度铁道部下属的研究设计和标准组织 (RDSO)。 RDSO 成立于 1957 年，整合了中央标准办公室（CSO）和铁路测试研究中心（RTRC）。该组织负责铁路机车车辆、永久轨道和其他相关方面的开发测试和应用研究。 RDSO 面临的挑战是将印度铁路打造成南亚和非洲市场柴油机车的真正供应商，需要开发满足严格的性能、可靠性和燃油经济性要求的柴油机车。
挑战
研究设计和标准组织 (RDSO) 的任务是将印度铁路打造成南亚和非洲市场柴油机车的真正供应商。我们面临的挑战是开发一款满足性能、可靠性、燃油经济性、耐撞性和操作员舒适度要求的内燃机车。机车需要在恶劣条件下经济、安全地运行数十年，并尽量减少停机时间。经受重复疲劳循环的部件的耐用性是一个主要问题，大多数装置在运行的前六年中行驶了超过 100 万英里，使用寿命接近 30 年。预计一些主要部件在二手设备市场上的使用寿命将超过 50 年。由于在如此大型、复杂的机器上运行物理测试需要大量的时间和成本因素，因此在缩短开发周期的同时实现这些目标尤其具有挑战性。 RDSO从1990年开始就使用仿真工具，但由于计算机和软件的限制，预处理时间太长。
解决方案
RDSO 使用 HyperWorks 进行结构分析，以评估组件的应力、挠度和模态分析。该模拟还用于指导设计人员在开发早期雕刻零件的基本形状和拓扑优化。 Altair HyperMesh 用于悬架动力学、驾驶室和其他子系统的隔振安装的详细分析，以及机车曲轴箱、气缸盖、活塞杆和其他往复运动部件的设计/开发和修改的验证柴油发动机。使用 Altair HyperMesh 对底架/平台进行应力分析，帮助 RDSO 优化底架，同时还能够减轻重量，这是由于 RE 驾驶室感应导致长度增加而造成的损失。 HyperMesh 现在作为验证和确认工具已成为标准设计模拟流程的一部分。

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.
