In the Condition Based Maintenance Lab (CBM LAB) research and training in condition monitoring, experimental tests and product development is conducted. In the laboratory, which has a focus on condition monitoring of railway and mechanical equipment (gears, roller bearings, etc.) there are currently the following test gear and equipment: 

  • Test rig for condition control of cracks in gears
  • Test rig for condition control of different sizes and types of gearboxes loaded with realistic torque and speed
  • Test rig for testing rolling bearings where radial force is controlled via computer and where accelerations and temperatures are to be analyzed with smart algorithms 
  • Equipment for measuring friction on rail and wear resistance
  • Equipment for measuring ultrasound, phased array and SAFT
  • Water tank for measuring cracks with ultrasound
  • Measurement trolley with winding current technology for detection of rail fasteners
  • Level gauge for track position measurements
  • Cracking gauge according to the resistance measurement method
  • Track profile gauge and surface finometer
  • Equipment for wireless transmission of measurement data from the railway

2019, a boogi, a rotatable undercarriage for trains and rail cars, was delivered to perform tests on the
university’s full-scale switches and crossings lab.

Track
At LTU, there is also a complete full-scale track switch mounted. It is 30 meters long and has been donated by the Swedish Transport Administration. The switch will initially be used to study point moter. Furthermore, there is also a 30 m long railroad track for detection of fasteners.
