关于客户
Trenitalia 是意大利主要的铁路运营商,负责管理该国铁路运输系统的开发、建设和维护。该公司的技术和研究部门采用先进技术为意大利铁路机队进行设计优化、应力强度结构检查和维护工程规划。该部门与信息技术部门合作,提高机械应力模拟能力和效率,并克服与模型大小、求解时间和硬件架构瓶颈相关的挑战。
挑战
意大利铁路运营商 Trenitalia 在管理该国铁路运输系统的开发、建设和维护方面面临着挑战。 Trenitalia 技术和研究部使用 ANSYS Mechanical 进行设计优化、应力强度结构检查和维护工程规划。然而,对更大分析模型和更短计算机响应时间的需求促使 Trenitalia 评估新的计算解决方案。他们必须克服的主要问题包括由于 32 位有限元程序使用的实际内存量而导致的模型大小限制、使用单处理器平台导致的较长求解时间以及内存和存储子系统中的硬件架构瓶颈。 -增加求解时间的系统。为了解决这些问题,Trenitalia 开始研究 64 位技术,其效率要求建议采用可扩展的 SMP 架构。
解决方案
Trenitalia 评估了基于 PC 的 AMD™ 64/EM64T 系统的 x86-64 技术,以应对其挑战。 AMD 处理器产生了良好的数学结果,全双工星形拓扑工作站平台将千兆字节的数据移入内存和存储子系统,或从内存和存储子系统移出千兆字节的数据。使用 ANSYS Mechanical 来解决一些实际生产测试模型的基准测试研究导致选择 Microsoft® Windows x64 Edition 操作系统,因为它的解决速度和性能效率。适用于 Windows x64 的 ANSYS 本机 64 位版本提供了双向 Win x64 SMP 工作站所需的分析软件,能够支持至少 16 GB 内存以及低延迟内存和存储子系统。高效求解百万自由度模型的成功尤其要归功于符合 ANSYS 并行标准的高性能稀疏求解器。

Case Study
IoT System for Tunnel Construction
The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. These issues are 'improving safety" and "reducing energy consumption". Mountain tunnels construction requires a massive amount of electricity. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Despite this, the amount of power consumption is generally not tightly managed. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. In other words, we needed to be able to visualize the amount of power being consumed. Safety, was also not being managed very rigorously. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. In other words, this new system would facilitate a clear picture of which workers were working in each location at the mountain tunnel construction site, as well as which processes were being carried out at those respective locations at any given time. The system would maintain the safety of all workers while also carefully controlling the electrical equipment to reduce unnecessary power consumption. Having decided on the concept, our next concern was whether there existed any kind of robust hardware that would not break down at the construction work site, that could move freely in response to changes in the working environment, and that could accurately detect workers and vehicles using radio frequency identification (RFID). Given that this system would involve many components that were new to Zenitaka, we decided to enlist the cooperation of E.I.Sol Co., Ltd. ('E.I.Sol') as our joint development partner, as they had provided us with a highly practical proposal.

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.

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.

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.
