155 A comfort improvement of the vertical vibration at the time of a Shinkansen high-speed run : A design method of the high speed bogie suspension 1^<st> report

Abstract

A design method of the high speed bogie suspension is proposed in this report. For improve the vertical oscillation of high speed Shinkansen vehicles, caused by the first order body bending, the primary and secondary suspension and damping should be optimized for avoiding the resonance between the bogie-bouncing, bogie-pitting and the body bending motion, in case that the bending stiffness of the car body could not be rised.
