360841 ACTIVE CONTROL OF AIRSPRING SECONDARY SUSPENSION TO IMPROVE RIDE COMFORT IN PRESENCE OF RANDOM TRACK IRREGULARITY(Vehicle,Technical Session)

Abstract

Aim of this paper is to explore the possible benefits brought by the use of active control of the airspring secondary suspension for high speed railway vehicles. The concept of the active suspension is developed and a prototype is tested. Then, the benefits of active suspension control are assessed by means of multi-body simulation.
