Random Vibration Properties of High-Speed Railway Vehicle Considering Random Parameters of Track Structure

Abstract:

Applied theory of vehicle/track coupled dynamic, random vibration properties of high-speed railway vehicles are researched in random parameters of fastener and ballast stiffness obeyed normal distribution and track irregularity combined the sample of artificial shortwave and the sample of low disturbance irregularity of high-speed railway in German with train speed increase. The results show that dynamic interaction of vehicle/track system and vibration responses of railway vehicle are increased with train speed increase, but the increase of wheel-set acceleration is much more. The parameters of high speed railway track structure (especially fastener and ballast stiffness) had much more impact to random vibration responses of vehicle/track system, so they should be optimized and remained in a narrow range.
