Influence of Rail Corrugation on the Brake Disc Vibration of High-speed Trains
摘要
Abstract
In order to explore the influence of rail corrugation on the vibration characteristics of high-speed train brake disc,a vehicle-track rigid-flexible coupling dynamic model was constructed.At the same time,track irregularity and rail cor-rugation excitation were added to simulate different working conditions.The vibration characteristics of the brake disc and the vibration transmission relationship between the axle and the brake disc were studied when the high-speed train passes through the rail corrugation section at different speed levels.The results show that when the brake disc passes through the corrugation section,the frequency range of severe vibration in the vertical direction is wider,and the frequency is concentrat-ed in the transverse direction.The rail corrugation is more likely to cause the vertical vibration of the brake disc;the root mean square value of the vibration acceleration of the brake disc decreases first and then increases with the increase of the wavelength,and increases with the increase of the wave depth.The vibration from the axle to the brake disc is amplified.The frequency of the vibration of the train caused by the corrugation is close to the natural frequency of the brake disc or the wheelset.Resonance intensifies the vibration and affects this change rule.The resonance can be avoided by changing the train speed through the rail corrugation section or changing the structure of the brake disc.This study provides a reference for the design of the brake disc structures.关键词
