Currently train axle inspections are required on every axle, every year. This is because an axle failure can lead to a derailment and significant damage. Train axle failures have caused major loss of life, with a consequential increase in both non-destructive testing and manual inspection that is expensive and disruptive to efficient rolling stock maintenance.This project aims to develop a method for detecting axle cracks on trains with on-board self-powered monitoring. The vision is to use continuous live monitoring of axles with low cost self-powered wireless systems that are easy to install and will replace expensive and disruptive NDT methods in maintenance sheds, eliminating inspections between major overhauls.It is intended to show that very significant cost reductions for train operators could be achieved as well as improvements in safety.The project will develop advanced low power signal processing and sensing techniques suitable for use in Perpetuum's harvester powered sensor platform on a test rig that will be built at Southampton University, using the key expertise of TWI Ltd., in NDT and fatigue cracks.This is a completely new approach to the serious issue of ensuring that cracks in train axles can be safely identified at reasonable cost.The project will be undertaken by experts at Perpetuum Ltd, University of Southampton and TWI Ltd...

目前，每年的每个车轴都需要进行火车轴检查。这是因为轴故障会导致出轨和重大损坏。火车轴故障导致了重大生命损失，由于非破坏性测试和手动检查的结果增加，这对于有效的滚动库存维护既昂贵且破坏性。愿景是利用与低成本的自动无线系统的连续实时监控，易于安装，并将取代维护棚中昂贵且破坏性的NDT方法，消除重大大修之间的检查。它旨在表明，非常重大的成本降低的培训运算师可以在安全方面进行改进。在NDT和疲劳裂缝中，使用Twi Ltd.的主要专业知识建造的测试钻机上的传感器平台。这是一种全新的方法，即确保可以在Perpetuum Ltd，University of Perpetuum ltd，Twi Lttd的专家中确保可以安全地确定火车车轴的裂缝。
