挑战
东京国立博物馆 (TNM) 成立于 1872 年,拥有超过 113,000 件文化资产,包括绘画、雕塑、陶瓷等。这些无价的文物经常需要在不同地点之间运输,这使得它们的包装和运输成为一项严肃的工作。 TNM 发现这些珍贵文物在运输过程中承受了意想不到且不可接受的振动载荷。博物馆几乎无法控制运输卡车的车辆动力学,这表明包装系统设计需要重新评估。 TNM 一直使用螺旋弹簧式“隔振器”来运输文化资产。这些隔离器位于装有艺术品的运输箱的底部。然而,随机实验室测试和试装卡车的结果表明,共振频率在 10 Hz 至 20 Hz 之间,处于卡车的激励频率范围(10 Hz 至 20 Hz)内,从而可能对文物造成损坏。
关于客户
东京国立博物馆(TNM)是日本最古老、最大的博物馆。它成立于 1872 年,保存了来自日本和周边亚洲地区的一系列考古物品和艺术品。博物馆藏品超过 113,000 件,其中包括多件藏品;资产包括绘画、书法、雕塑、建筑、金属制品、陶瓷和刀剑等。这些文物通常需要在不同地点之间运输,例如 TNM 和寺庙。博物馆非常重视评估其运输过程和包装系统,以确保这些无价且不可替代的物品的安全和保存。
解决方案
TNM 与 Altair® 和咨询公司 eXcearch LLC 合作,查明异常振动的根本原因。该团队制定了一种模拟驱动的研究方法,结合了计算机辅助工程 (CAE) 和物理测试。他们创建了一个虚拟包装盒,其中四个隔离器以 0 度和 45 度角放置,并测试了两个重量:176 公斤和 88 公斤。该团队在虚拟箱的底部安装了三轴加速度计,并在实验室中使用“振动台”来测量系统对受控频率激励的响应。根据他们的物理测试,该团队发现随着输入加速度的增加,共振频率会转移到较低的范围。然后,团队使用物理测试的结果进入模拟模式。他们应用了 Altair 商业开发的 MBD 技术。他们使用用于机械系统仿真的 MotionSolve® 软件、用于模型组装的 MotionView® 和用于结果可视化的 HyperView® /HyperGraph®,创建了虚拟盒的虚拟模型。

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.

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.”
