MBS-calculation safety against derailment of an electric track vehicle

Customer: ROBEL Bahnbaumaschinen, Germany

Project tasks

• 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)

Our Approach

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.

Customer benefit

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).
