What is it about?

The railway vehicles random analysis procedure (RVRAP) based on the pseudo-excitation theory which can help engineer to predict the structural random response of railway vehicle quickly and accuratly.

Why is it important?

Random vibrations are observed in vehicles moving on the railway because essential sources of excitation are random track irregularities. Knowledge on rapidly and reliably gathering random responses from projects to compute the PSD of acceleration and the fatigue stress concentration will be used to predict running quality and fatigue life. Our work (RVRAP) can help designers have strengthened their competitiveness


I hope this article helps the engineer who might consider random vibration is very important in vehicle dynamics design and the RVRAP also lead to a simple solution for engineering application.
