Brake testing on open line
Measure the braking performance and associated forces for the type approval or development of any kind of rolling stock.
Objectives
- Develop, validate and measure braking performance during:
– Tests carried out on a trainset, a convoy or a traction unit
– Slip brake tests on all kinds of rail vehicles - Characterize under normal and degraded wheel/rail adhesion: Emergency brake, service brake, locking brake, parking brake
- Determine key parameters: Equivalent response time, jerk, corrected stopping distance, average equivalent deceleration
- Monitor related parameters: Pressure in brake cylinders, brake component temperature, axle speed, test conditions (temperature, relative humidity)
- Characterize and qualify brake parts
- Measure forces applied to the wheels and discs
