3204 The Influence of the Wheelset Static and Dynamic Unbalance on the Wheelset Vibration

Abstract

This paper describes the jnflucnce of the wheelset stanc and dynamic ロ nbalance on 【he wheelset vibration ． In 由 e case of the model used in numerical analyses ， smaUer static unbalance means Iager dynamic unbalance and larger lateral vibration of the wheelset ． So ， it can not be said that the policy of reducing static unbalance 【 o the mlnimum
