This paper brings to view a new passive approach regarding the reduction of the flexible carbody vertical bending vibration of railway vehicles via two anti-bending bars fixed onto the longitudinal beams of a carbody underframe. The anti-bending bars operate as elastic elements limiting the rotation of the carbody cross-sections and thus increasing the bending carbody frequency. The anti-bending bars are dimensioned so that the frequency of the first bending mode of the carbody to be convenient in terms of ride comfort. The effectiveness in the use of the anti-bending bars is proven by the lowering of the vibration level and improvement of the vehicle ride comfort.
