关于客户
Energy Absorbent Systems, Inc. 是碰撞缓冲垫、冲击衰减器和其他能量吸收安全装置设计和制造领域的全球领先者。该公司的产品旨在保护高速公路作业区的人员和设备免受车辆交通的影响。该公司总部位于伊利诺伊州芝加哥，在加利福尼亚州罗克林设有专门的产品开发实验室和认可的测试设施，并在阿拉巴马州和印第安纳州设有制造工厂。该公司的安全系统已在美国全部 50 个州和全球 60 个国家/地区使用，并帮助挽救了超过 25,000 条高速公路上的生命。
挑战
Energy Absorbent Systems, Inc. 是防撞缓冲垫、冲击衰减器和其他能量吸收安全装置设计和制造领域的全球领先者，其 TMA-180 车载衰减器面临着挑战。该装置由铰接钢框架组成，其中包含吸能充气铝制挡板，从停放的施工车辆的后部延伸出来，以保护高速公路作业区的人员和设备免受车辆交通的影响。该公司找到了一家更可靠、更经济的液压缸供应商，为框架旋转提供动力。然而，气缸几何形状和负载的差异需要重新设计连接气缸和框架的 U 形连杆。面临的挑战是尽可能快速、可靠地执行重新设计，以缩短改进产品的上市时间。
解决方案
该公司使用 ANSYS Workbench 重新设计了 U 形连接装置。该软件使工程师能够确定减少零件厚度的应力和变形，并评估替代材料以获得足够的零件强度。 Workbench 的双向 CAD 关联性使工程师能够快速来回迭代，以达成最佳设计。 Workbench 集成到 Autodesk Inventor 中，这是能量吸收使用的设计工具。这种集成使工程师能够通过单个菜单选择提取零件几何形状来构建仿真模型，然后根据仿真结果快速修改 CAD 几何形状。该循环可以重复多次，无需重建仿真模型，从而节省大量时间和资源。

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.
