Abstract

A suspension system for a train vehicle includes at least one inerter to minimize track wear. Track wear may be measured by direct measures such as wear work, or indirect measures such as yaw stiffness. “Minimizing” track wear means that such measures are reduced below values which are achievable with conventional technology while maintaining acceptable values of other performance metrics, such as ride comfort or least damping ratio. The suspension system may comprise at least one damper connected in series with the at least one inerter. The suspension system may be the primary or the secondary suspension system of a train vehicle.
