Effects of Modal Parameters on Ride Comfort Index under Harmonic Excitation

  • An expression of the vertical ride comfort index of rail vehicles was derived by modal coordinate transform and described by modal parameters.The effects of modal parameters,i.e.modal frequency and mode,on the ride comfort index were studied by taking a secondary suspension system of a railway vehicle with 15-DOFs as an example.The research indicates that the comfort index is affected greatly by the modal frequencies of the vehicle body,different modal damping ratios have obvious different effects,and the effect of the first order modal damping ratio is greater than that of the second order modal damping ratio is.
