Measurements and simulations of rail vehicle dynamics with respect to overturning risk

Rail vehicles are exposed to strong lateral influences through curves, track imperfections andcrosswind leading to large deflections of the vehicle suspension systems and carbody displacements.In turn this increases the risk of vehicle overturning. In the present work multibodysimulations are performed in order to study the motion in the secondary suspension. Suspensiondeflection measurements on a fast test train were carried out and used for validation ofthe simulations. The simulations show good agreement with the measurements and representa good tool to predict the motion in the secondary suspension.
