Boggi strengthens the university's test environment for railways

Published: 21 October 2019

In a new project on digitized state control of railway switches vibrations that occur when trains pass a railway switch are measured wirelessly to detect wear and damage in the railway switch. With this knowledge, preventative maintenance can be more effective.

"With pattern recognition and neural networks, the wear and damage in the track gear must be correlated with the measured vibrations," says Jan Lundberg, professor in operations and maintenance engineering at Luleå University of Technology.

This should result in an automated decision support for the Swedish Transport Administration, based on the transmission of very large amounts of vibration data in the range 1-40,000 Hz, with regard to preventive maintenance of switches.

To do this, the researchers have been given a boogi, a rotating undercarriage for trains and rail cars, to perform tests on the university's full-scale switchgear lab.Luleå University of Technology is the only Swedish university that now has a complete full-scale railway switch on campus. It is 30 meter and it is Professor Jan Lundberg who received the switch as a gift from Trafikverket, who for ten years he conducted research in collaboration with.

The project includes a total of SEK 5 million and is being implemented in collaboration with Bombardier, the Swedish Transport Administration and Infranord. The project is funded by Formas.
