 note = {The previous report discussed the lasting longitudinal vibration of a bogie car, which was the 1st modal one excited by the vertical track irregularities. The present paper describes analytical results of the effects of the rubber stiffness on the longitudinal vibration characteristics. The rubber used for fixing the primary damper is a sort of vibration isolator acting in series with the damper, and its stiffness has to be lowered in order to allow the damper to incline with the horizontal distance between the truck frame and the axle box. However, when the stiffness is too low, the damping effect deteriorates. In the realistic range of lowered stiffness, the 1st modal longitudinal vibration grows with the lowered stiffness, and when the stiffness is lowered further, the vibration due to the truck pitching increases markedly.},
