关于客户
DSA 是一家海洋工程咨询和软件公司,为海洋服务提供商、项目开发商、海洋工程师、造船工程师、海洋学家和任何从事水上业务的人提供解决方案。该公司的解决方案使这些利益相关者能够评估海流、风和波浪对其船舶、技术和项目的影响。 DSA 生产两种先进的水动力海洋分析软件包 ProteusDS 和 ShipMo3D,还为海洋企业提供一系列海洋工程咨询服务,通常使用 ProteusDS 和 ShipMo3D。
挑战
DSA 是一家海洋工程咨询和软件公司,在为船舶和海洋结构创建高质量的水动力网格和模型方面面临着重大挑战。在 CAD 软件中创建高质量网格的任务是一项复杂的任务,因为网格通常不能很好地适应流体动力学解决方案,而流体动力学解决方案需要封闭表面来解决流体动力学效应,例如非线性流体静力学和 BEM 解决方案。为了建立精确的船舶流体动力学模型,DSA 的软件之一 ShipMo3D 需要开发船体网格。这可以通过创建船体线或导入使用第三方软件创建的 OBJ 网格文件来实现。然而,这两种方法都很耗时,并且常常会导致网格不够理想。
解决方案
为了克服这一挑战,DSA 求助于 Altair HyperMesh,从 CAD 文件创建这些网格文件,所用时间仅为输入船体线数据所需时间的一小部分。 Altair HyperMesh 使 DSA 能够有效调整网格,并确保使用最高效、最准确的网格。将网格导入 ShipMo3D 后,该软件使用基于镶板表面的边界元方法来确定船舶对波浪和运动的水动力响应。这使得用户能够确定船舶的俯仰和横摇响应、垂直和横向加速度以及整体操纵和适航特性等。同样,DSA 的另一款软件 ProteusDS 使用水动力网格来计算水动力载荷。 DSA 还开始定期使用 Altair AcuSolve 和 Altair Virtual Wind Tunnel 作为其咨询工作的一部分,在其软件中形成集成,从而可以轻松导出 AcuSolve 和 VWT 的结果。

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.”
