挑战
Swift Engineering, Inc. 是一家产品开发公司，在设计、开发和制造高性能先进复合材料车辆、无人系统和自动化机器人方面拥有 30 多年的经验，其 Swift020 无人机系统 (UAS) 面临着挑战。面临的挑战是定义 Swift020 无人机上使用的维护工具的最大重量规范。之所以引起担忧，是因为无人机的飞行表面是最小规格的，掉落在结构上的重型工具可能会造成无法修复的损坏、停机和昂贵的部件更换。目的是确定维护工具的最大重量，如果从 0.762 米的标称高度掉落，不会对 Swift020 无人机的任何部分造成永久性损坏。
关于客户
Swift Engineering, Inc. 总部位于加利福尼亚州圣克莱门特，是一家产品开发公司，在设计、开发和制造高性能先进复合材料车辆、无人系统、全尺寸演示器、按图生产方面拥有 30 多年的经验和自动化机器人技术。 Swift 专门从事轻质复合材料结构、部件和车辆的设计、开发和制造。 Swift 成立于 1983 年，是一家领先的高性能赛车开发商，自 1997 年以来一直将其复合材料人才深度应用于航空航天业。Swift 已成为首屈一指的飞行器设计商和制造商，成功的 KillerBee 无人机就证明了这一点航空系统 (UAS)、波音·西科斯基联合多用途 (JMR) 演示机、Eclipse 概念喷气机计划以及许多其他类似的航空航天和海洋按图生产复合材料制造项目。
解决方案
为了解决这一挑战，Swift Engineering 采用了 RADIOSS 显式动态冲击仿真。 UAS 的显式模型是在 HyperMesh® 中生成的，并受到钢穿透器以定义的落下能量的影响。使用最大复合压缩应变与冲击能量和受冲击复合材料的极限应变的参数曲线来得出最大工具重量的规格。在 HyperMesh 中生成了 Swift020 的全尺寸模型。主要结构部件由石墨、玻璃纤维和 Kevlar® 环氧高级复合材料组成，使用 RADIOSS 中的 MAT25 材料属性进行建模。侵彻器被建模为直径 0.0254 米的半球形尖端杆。对穿透器施加 3.867 m/s 的初始速度 (INIVEL)，以利用能量守恒模拟 0.762 米的跌落。使用材料卡中的穿透器的密度来调节冲击能量。

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.
