PJM enables significant cost and time savings when replacing test drives with simulations.

The results of the multi-body simulation increase the dynamic system understanding and show the approval capability of a vehicle in the development stage.

Our highlights:

Replacement of test runs for running behavior and derailment safety (EN14363)
The dynamic track tests can be partially replaced by simulations using validated calculation models. Accelerations, wheel-rail forces etc. are calculated. The evaluation of driving stability is also possible in this way, without turning on special wheel profiles for high conicity.

Ride comfort (EN12299)
The evaluation of ride comfort is usually carried out together with the dynamic track tests. Simulations can also be used here.

Impact test (EN12663-2)
Significant reduction in the number of overrun impact tests for freight wagon types with many different wagon lengths.

Load determination
Determination of component loads for the strength verification of control arms, bearings and other components.

Wear
Support in the selection of tread profiles to minimize wheel and rail wear, as well as determining the cause of unusually high wear.

Train path price model
Classification of the vehicle in SBB's wear-based train path price, or verification of the classification if this is carried out by the vehicle manufacturer.

Special vehicles
Simulation of special vehicles (e.g. rolling road) with many wheelsets and special running gear or coupling mechanisms for radial positioning of the wheelsets

Cost-effective support
For smaller projects or unusual operating conditions of vehicles.
