关于客户
航空母舰联盟 (ACA) 是英国航空航天和国防领域行业领导者之间的独特合作关系。 ACA 负责交付伊丽莎白女王级航空母舰,这是英国有史以来建造的最大的军舰。该联盟由 BAE Systems、Babcock、Thales 和英国国防部组成。 ACA 致力于为英国皇家海军提供一流的海军能力,因此,他们不断寻求创新的解决方案来改进其海军舰艇的设计和制造流程。
挑战
航空母舰联盟 (ACA) 在海军舰艇项目的概念和初步设计阶段面临重大挑战。设计人员经常需要使用有关船舶主要结构设计驱动因素的有限数据。这通常会导致很大程度上主观的设计方法,这可能会导致效率低下,甚至从一开始就锁定结构问题。为了纠正任何问题,最终产品可能会增加材料使用、重量和不必要的复杂性,以及高昂的设计和制造成本。 ACA 试图在海军舰艇设计的独特要求下评估仿真驱动设计的潜力。
解决方案
ACA 与 Altair ProductDesign 合作,应用优化技术,为船舶的一系列结构区域提供高效、一次性正确的设计解决方案。人们感兴趣的领域之一是航空母舰的飞行控制(FLYCO)模块。 FLYCO 模块结构由支撑在上下舷舱结构之间的大面积玻璃区域组成。这些舷侧结构需要满足固有频率和偏转目标,因此会受到质量和刚度复杂相互作用的影响。首先采用拓扑优化来确定加强腹板在模块封装内的最佳全局定位。随后进行另一轮拓扑优化,以确定这些腹板内的最佳载荷路径,从而可以在不影响结构性能的情况下切割开口。最后,采用尺寸和形状优化来微调板的厚度和开口尺寸,以最大限度地减少质量和设计复杂性,同时满足设计目标。

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.

IoT-based Fleet Intelligence Innovation
Speed to market is precious for DRVR, a rapidly growing start-up company. With a business model dependent on reliable mobile data, managers were spending their lives trying to negotiate data roaming deals with mobile network operators in different countries. And, even then, service quality was a constant concern.

Digitize Railway with Deutsche Bahn
To reduce maintenance costs and delay-causing failures for Deutsche Bahn. They need manual measurements by a position measurement system based on custom-made MEMS sensor clusters, which allow autonomous and continuous monitoring with wireless data transmission and long battery. They were looking for data pre-processing solution in the sensor and machine learning algorithms in the cloud so as to detect critical wear.

Cold Chain Transportation and Refrigerated Fleet Management System
1) Create a digital connected transportation solution to retrofit cold chain trailers with real-time tracking and controls. 2) Prevent multi-million dollar losses due to theft or spoilage. 3) Deliver a digital chain-of-custody solution for door to door load monitoring and security. 4) Provide a trusted multi-fleet solution in a single application with granular data and access controls.
Case Study
Vehicle Fleet Analytics
Organizations frequently implement a maintenance strategy for their fleets of vehicles using a combination of time and usage based maintenance schedules. While effective as a whole, time and usage based schedules do not take into account driving patterns, environmental factors, and sensors currently deployed within the vehicle measuring crank voltage, ignition voltage, and acceleration, all of which have a significant influence on the overall health of the vehicle.In a typical fleet, a large percentage of road calls are related to electrical failure, with battery failure being a common cause. Battery failures result in unmet service agreement levels and costly re-adjustment of scheduled to provide replacement vehicles. To reduce the impact of unplanned maintenance, the transportation logistics company was interested in a trial of C3 Vehicle Fleet Analytics.

3M Gains Real-Time Insight with Cloud Solution
The company has a long track record of innovative technology solutions. For example, 3M helps its customers optimize parking operations by automating fee collection and other processes. To improve support for this rapidly expanding segment, 3M needed to automate its own data collection and reporting. The company had recently purchased the assets of parking, tolling, and automatic license plate reader businesses, and required better insight into these acquisitions. Chad Reed, Global Business Manager for 3M Parking Systems, says, “With thousands of installations across the world, we couldn’t keep track of our software and hardware deployments, which made it difficult to understand our market penetration.” 3M wanted a tracking application that sales staff could use to get real-time information about the type and location of 3M products in parking lots and garages. So that it could be used on-site with potential customers, the solution would have to provide access to data anytime, anywhere, and from an array of mobile devices. Jason Fox, Mobile Application Architect at 3M, upped the ante by volunteering to deliver the new app in one weekend. For Fox and his team, these requirements meant turning to the cloud instead of an on-premises datacenter. “My first thought was to go directly to the cloud because we needed to provide access not only to our salespeople, but to resellers who didn’t have access to our internal network,” says Fox. “The cloud just seemed like a logical choice.”
