Dynamic Tests on Wheelset Roller Rig
Dynamic Tests on Wheelset Roller Rig
BU300 is a roller rig for full scale wheelsets. It can reach a maximum speed of 300 km/h while it controls vertical and lateral loads and the relative wheelset-rail yaw angle.
The rails are two rings with the typical UIC-60 profile. Through the test rig controller is possible to reproduce realistic straight and curve running conditions, including acceleration and braking.
The test rig can be used for various purposes like:
- Rolling contact fatigue tests
- Wheelset dynamics analysis
- Calibration of instrumented wheelsets to measure wheel-rail contact loads
- Rolling fatigue tests on resilient wheels or special wheels designs
