Der Einfluss von Ausrüstung und Zuladung auf die vertikale Biegeschwingung eines Eisenbahn-Personenwagens

The natural frequency of the vertical bending oscillation was experimentally determined by Schindler Waggon Altenrhein AG at various stages during manufacturing of a passenger coach for Swiss Federal Railways (SBB). Based on comparisons with the calculated values which take into account only the effect of the mass conclusions are drawn with regard to the stiffening effect of the body structure
