高速动车组会车横向振动特性及识别方法研究
research on transverse vibration characteristics and recognition methods of high-speed trains passing each other
摘要
Abstract
During high-speed operation,a multiple unit train may encounter another multiple unit train traveling in the opposite direction on an adjacent track.This movement state is referred to as passing movement,which can lead to an intensification of lateral vibrations of carbody and significantly affect the amplitude of the carbody's lateral acceleration data.If this impact is not identified and addressed,it would affect the validity of the track condition assessment results output by the inspection vehicle.Therefore,it is necessary to effectively mark the passing state that occurs during the operation of the multiple unit train.This paper took the lateral acceleration data collected by high-speed comprehensive inspection trains as the research object.By analyzing a large amount of meeting data,we obtained the data characteristics of lateral acceleration of the vehicle body when the high-speed trains pass each other.The high-speed train generates two lateral vibrations with opposite directions.The first vibration is more severe than the second vibration.Both vibrations converge quickly in a relatively short period of time.The interval between two vibrations was related to the length and relative operating speed of the two high-speed trains with meeting.Correspondingly,the carbody's lateral acceleration data shows four distinct peak points,with the first peak point has the same sign as the fourth peak point.The amplitude of the carbody's lateral acceleration at the second peak point is significantly greater than that at the fourth peak point.The half-wavelength of the two vibrations is mainly distributed within the range of 6～9 meters.The interval distance between the two lateral vibrations is concentrated near 100 meters and 200 meters,with actual intervals varying based on different speed differences.A passing identification method based on the characteristics of the lateral acceleration data of the train body was proposed.By analyzing the actual measured data with the proposed method,the results show an identification success rate of 100%,verifying the effectiveness of the method.关键词
