TrackSafeTM
Track Geometry / Vehicle Interaction
TrackSafe uses the real-time dynamic simulation of multiple vehicle types and traveling speeds to predict and locate potentially unsafe areas in track. This approach more comprehensively considers the result of repeated, but perhaps non-defective anomalies in the track geometry. Furthermore, it considers the effect of combinations of track geometry parameters.
| TrackSafe
is designed to operate on-board a track geometry
car traveling at full track speed. The system
allows the selection of the number and type of
vehicles that will be simulated, as well as the
traveling speeds to be simulated for each
vehicle. Response predictions for each vehicle
include the vertical displacement and
acceleration of the carbody, as well as carbody
roll and wheel unloading. These values are then
compared with dynamic response safety limits.
Output reports identify areas of track that are
predicted to result in unsafe vehicle response
and include the type of response (e.g. wheel
unloading, harmonic rock off, etc.) and the
vehicle speed(s) at which the unsafe response
occurs. |
| Tracksafe provides a comprehensive assessment of track safety that can help locate areas where poor, but non-defective track geometry may lead to unsafe vehicle performance. By simultaneously analyzing the response of multiple vehicle types and a range of traveling speeds in real-time, TraskSafe provides a more complete inspection of the existing track geometry and can be used to reduce track geometry-related derailments. |
