Canada has the 5th largest rail network in the world and rail service operators are challenged to maintain the trackage to provide safe and efficient services. Severe rail wear, surface damage, ballast disruption, and other problems often result in revenue rail vehicle speed reduction, service disruption, unscheduled engineering works, and sometimes catastrophic failure. Rail vehicle mounted inspection systems gather data autonomously across the rail network in an attempt to identify 'outlier' locations.The National Research Council Canada (NRC) currently supplies a strain-gauge instrumented wheelset in an attempt to understand critical vehicle track interaction (VTI) parameters such as the wheel-rail contact condition, but this technology can only infer such information.A Sheffield based technology company Peak to Peak Measurement Solutions Ltd. (PktoPk) specialise in the supply of embedded ultrasonic sensor systems for the non-invasive measurement of dynamic machine contacts in the international rail, marine, automotive, manufacturing, and renewables markets.This grant will fund the development of PktoPk's existing rail-mounted ultrasonic sensor technology to be deployed onto an instrumented wheelset. This will be the first time ultrasonic transducer arrays have ever been embedded into the wheelset of an on-track railroad vehicle. The sensors will provide autonomous geotagged real-time measurements of the following key VTI parameters:* Wheel-rail contact area, shape, location of contact, flange contact, wheel climb, problems with gauge, cyclic top, wheel unloading points, understanding of pummelling (distribution of contact, wear/damage)* Understanding rail wear/rail head defects* Wheel-rail contact pressure and stiffness (inferring surface roughness and traction)* Lubricant/3rd body layer conditions; sand, ice, leaves on the line* Wheel axle yaw/angle of attackMuch of this information cannot be measured using existing inspection vehicle mounted sensor products. The new 'ultrasonic NDT wheelset' can be installed on dedicated inspection vehicles, revenue service vehicles, or towed coaches, and can capture critical data at full revenue-service speeds.Having up-to-date quantitative geotagged VTI data across the rail network will support next generation intelligent engineering business systems providing critical real-time information to rail service operators. The result will be a rich stream of data laying foundations of digital connectivity that will safely deliver us to our next century of efficient operations with advanced maintenance scheduling, maximum rail vehicle operating speeds and highest revenue vehicle throughput.This collaboration will allow our partner NRC to offer a far superior instrumented wheelset product solution based on the embedded ultrasonic technology developed at The University of Sheffield' and PktoPk.

加拿大拥有世界第五大铁路网络，铁路服务运营商面临着维护轨道以提供安全高效服务的挑战。严重的轨道磨损、表面损坏、道碴中断和其他问题通常会导致收入铁路车辆速度降低、服务中断、计划外的工程工作，有时甚至是灾难性的故障。铁路车辆安装的检测系统在整个铁路网络中自动收集数据，试图识别“异常值”位置。加拿大国家研究理事会（NRC）目前提供了一种应变仪测量轮对，试图了解关键的车辆轨道相互作用（VTI）参数，如轮轨接触条件，一家位于谢菲尔德的技术公司Peak to Peak Measurement Solutions Ltd.（PktoPk）专门提供嵌入式超声波传感器系统，在国际铁路、船舶、汽车、制造业和可再生能源市场上，对动态机器接触进行侵入式测量。这笔赠款将资助PktoPk现有的轨道安装超声波传感器技术的开发，该技术将部署在仪表轮对上。这将是超声波换能器阵列首次被嵌入轨道铁路车辆的轮对中。传感器将提供以下关键VTI参数的自主地理标记实时测量：* 轮轨接触面积，形状，接触位置，凸缘接触，车轮爬升，轨距问题，循环顶部，车轮卸载点，对撞击的理解（接触分布、磨损/损坏）* 了解钢轨磨损/轨头缺陷 * 轮轨接触压力和刚度（推断表面粗糙度和牵引力）* 润滑剂/第三本体层条件;线上的沙子、冰、树叶 * 轮轴偏航/迎角使用现有的检测车辆安装的传感器产品无法测量大部分信息。新的“超声波无损检测轮对”可安装在专用检测车辆、收入服务车辆或牵引式客车上，并能以全收入服务速度捕获关键数据。在整个铁路网络中获得最新的定量地理标记VTI数据将支持下一代智能工程业务系统，为铁路服务运营商提供关键的实时信息。其结果将是丰富的数据流奠定了数字连接的基础，将安全地为我们提供下一个世纪的高效运营和先进的维护计划，最大的轨道车辆运行速度和最高的收入车辆吞吐量。这种合作将使我们的合作伙伴NRC能够提供基于谢菲尔德大学开发的嵌入式超声波技术的上级仪表轮对产品解决方案，PktoPk.
