Chinese CRRC is the world's largest rail and high-speed train manufacturer and 60 percent of the world's high-speed rail system is being manufactured in China, and there are more than 22,000 km of railways for high-speed rail. The fastest now-rolling train in China runs 350 km / h (design service speed is 400 km / h).
"We can provide robust and reliable Prognostic and Health Management (PHM) solutions for high speed trains and it will be based on so-called intelligent cloud services" says Janet Lin, Associate Professor in Operation and Maintenance Engineering at Luleå University of Technology and Coordinator of the CRRC-LTU – Research center. The CRRC -LTU centered is exclusively focused on focus on maintenance technology.
One of the more common technical problems on high-speed trains is axle bearings so it will be one of the areas where the new system will detect and prevent problems prior to functional failure. The system will also provide a forecast of when and how the problem has to be addressed. Chinese Engineers are competent and what we are doing is to provide the complementary knowledge needed to make the correct decision regarding maintenance and develop predictive and prescriptive technologies and business solution relevant for the operation of High speed trains at 350 km an hour.
The researchers at the Division of Operation and Maintenance Engineering at Luleå University of Technology consisting of more than 40 researchers are globally recognized for their capability and competence and plays an important and leading role when it comes to research in the field railway maintenance.
“It is an honour that world’s largest company has initiated project that will facilitate development of not only reliable and cost effective train but also it will make significant contributions towards making these train sets failure free facilitating high level of safety in operation. It is in the field of operation and maintenance that we primarily discuss research collaboration," says Uday Kumar, Director JVTC and Professor of Operation and Maintenance Engineering at Luleå University of Technology.
In Sweden we have a total of 14,000 km of railway Track. However, Government has proposed to build high speed train with an investment of 230 billion SEK.
The project Prognostic and Health Management for Rail Transportation Equipment – Application studies on maintenance strategies of EMU axle bearing and collaborative maintenance management technologies is being carried out in cooperation with the Chinese company CRRC Sifang - China South Locomotive and Rolling Stock Industry Corporation - and will last until 2019. This project is divided into two sub-projects, the other part is about maintenance strategies and prognostic of axle bearings
During September 2017, the CEO of CRRC and the Vice Chancellor of Luleå University of Technology signed a letter of Intent for cooperation in field of O&M of railway system.
