MBS-calculation safety against derailment of an electric track vehicle
Customer: ROBEL Bahnbaumaschinen, Germany
MBS-calculations to evaluate safety against derailment in track twists based on the EN14363:2019
Investigation with cranes in transfer mode and in two different working positions
Determining of existing reserves of the lifting load
Presentation of the results regarding the EN14033-2:2017 appendix H to the technical supervisory authority (TAB)
PROSE created an MBS model of the track vehicle and simulated runs through critical curves with superelevation and maximum track twist considering the specifications from the EN14363 for the vehicle in transfer mode and in two different working positions with corresponding crane position and lifting load.
With the MBS-simulations PROSE was able to prove the safety against derailment of the track vehicle in twisting sections of track by calculations and to determine the existing reserves of the lifting load in the two working positions. Furthermore, the results are used in the approval process as a presentation for the technical supervisory authority (TAB).
