The authors have been developing rails for hand straps (RHSs) to improve rigidity of railway vehicle carbodies. The RHSs have been designed for a certain commuter type railway vehicle, and the effects have been verified with the excitation tests on the rolling stock test plant. In this study, RHSs improving damping characteristics are newly proposed to directly reduce the bending vibration of the carbody. Finite element model corresponding to the test vehicle is produced and the performance of the RHSs is evaluated in this model. The simulation results show that the RHSs installed with viscoelastic material successfully reduce acceleration power spectral density (PSD) on the carbody independent of the position in the carbody.
