Compilation and preparation of parameters for modelling and simulation
Determination of the braking scenario to be considered
Creation of a multi-body simulation model (MBS model) of the cogwheel supporting wagon to be investigated as well as of the coupled train configuration
Execution and evaluation of the simulation
Documentation in a verification report
PROSE is to prove by simulation that derailment safety is given with the new requirements and to develop a set of arguments that can be submitted to the BAV to adapt the driving service regulation.
In a first step, PROSE compiled all the parameters required for modelling and simulation on the basis of customer data. Subsequently, the braking scenario was determined and agreed with the customer. PROSE created the multi-body simulation model (MBS model) of the container car in the required modelling depth. The overall model of the train set included a simplified MBS model of the necessary vehicles for the combinations to be verified in addition to the carrying car to be investigated. PROSE simulated the operationally most critical cases and recorded the results and evaluation of the simulations in a verification report for the attention of the approval authority.
The customer received a verification report for the approval documentation, which clearly and comprehensibly documents the mathematical proof of safety against derailment of the cogwheel carrier car. On the basis of the proof, the customer was able to obtain the adjustment of the driving service regulation from the BAV.
