Description
Summary:Detection of derailments based on the irregular pattern of motion of an axle, bogie, or even an entire vehicle is becoming increasingly important due to extensive track use and higher frequency of freight and passenger operations. The current technology detects the irregular oscillation of wheels, and is therefore limited to tracks with sleepers and ballast. During a derailment, the wheels begin to oscillate violently and the detection device is triggered. However, this system faces a challenge due to the increasing use of slab tracks that have no or only a minimal number of sleepers. Knorr-Bremse, in a joint project with the Technical University of Berlin, is currently testing a new electronic derailment detector for these types of tracks. The new, model-based validation process will focus on a detection algorithm that can be used for all vehicle types.
