关于客户
Ankers 是一家通过提供模拟、设计和开发服务来支持客户开发新产品的公司。该公司专注于从头开始开发特种汽车，包括为多家欧洲和中国汽车原始设备制造商和一级供应商开发电动汽车和内燃机汽车、一次性超级汽车和赛车。 Ankers 的工程师致力于走在技术的最前沿，并正在使用最先进的工具和开发方法。他们选择的工具集之一是 Altair 的 HyperWorks 套件，Ankers 的仿真团队自 2014 年成立以来一直在使用该套件。这些工具已用于众多仿真和开发项目，其中包括结构分析和优化任务。
挑战
Ankers 是一家为汽车原始设备制造商和一级供应商提供仿真、设计和开发服务的公司，面临着确定制动盘和制动片的热影响对车辆制动距离的挑战。车辆减速时制动器产生的摩擦热会对制动系统产生各种负面影响，包括制动盘热裂纹、过早磨损或制动失效，以及由于高温下摩擦系数变化而导致制动距离增加。目标是通过理解和减轻这些影响来优化系统行为。面临的挑战是通过联合仿真表明在考虑热效应时仿真结果会更加准确，并向现有和未来的汽车客户展示公司的联合仿真能力。
解决方案
Ankers 使用联合仿真方法，应用 HyperWorks 套件的多体动力学工具 MotionView 和使用一维方法模拟和优化多学科系统的解决方案 SolidThinking Activate。本研究中使用的模型是整车模型和制动系统模型，包括制动盘和制动片。这两种模型都是在 MotionView 中创建的，使用了该软件通过其车辆库提供的各种系统模板。为了考虑制动过程中能量转换引起的热影响，多体系统与 Activate 进行了联合仿真。这使得工程师能够研究盘垫接触引起的温度对制动距离的影响。联合仿真模型是在 MotionView（多体系统加高级驱动程序）和solidThinking Activate（摩擦热相关模型）中建立的。

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.
