Dynamic behavior addresses the modeling of rail vehicles as multi-body systems and simulation of their operation behavior with respect to the frequency and time range. A layout with respect to driving properties has to consider quality criteria determining ride comfort and safety over the entire speed range and for different modes of operation. This multicriteria optimization task is solved by numerical optimization procedures.
Durability is very important for rail vehicle components like bogie frames.
By a more precise consideration of the states of operation an improved layout can be achieved.
