Disk Brake Element Chatter Analysis and Strength Evaluation forRailway Vehicle System

摘要：

Friction brake is still an absolutely necessary way of brake in high speed vehicle today.Complex nonlinear vibration phenomena appear in friction brake system because of dry frictionbetween friction pairs.The resulted brake squeal and brake chatter may cause strength failure andfatigue damage of the disk brake element.Therefore,it is necessary to consider chatter in strengthcalculation and structure life prediction of disk brake element.In this paper,the finite element modelof disk brake element is built.Vibration displacements and dynamic stresses are calculated for chattercharacter analysis and strength evaluation.
