Abstract: | The dynamic design of railway vehicles is often supported by numerical simulation performed by means of Multibody codes. Such
methodology allows to define vehicle suspensions characteristics so as to meet running safety requirements and, in the case
of passenger vehicles, to achieve an adequate comfort level. However, the effectiveness of the numerical model in the prediction
of actual vehicle behavior may fall short of requirements if the model is not sufficiently accurate. Experimental validation
can help to ensure reliability of the numerical models. In order to solve the problem, this work proposes to use experimental
tests on scaled prototypes on roller-rig for preliminary validation of the numerical model. |
