Abstract

With lightweight design of high-speed train, flexible vibration of vehicle body becomes more and more significant in running process. When the excitation frequency of track geometric irregularity with a specific wavelength is close to natural vibration frequencies of the vehicle system, the resonance between the vehicle system and the irregularity excitation can happen to affect the train operation safety and riding comfort. Here, to study the sensitive wavelength of high-speed railway track geometric irregularity, based on the vehicle-track coupled dynamics theory, a high-speed train -track coupled dynamic model considering flexible vibration of car body was established, and effects of wavelength variation of different types of track irregularity on dynamic performance of high-speed train were systematically studied. Then, the most unfavorable wavelength and sensitive wavelength range of different types of track geometric irregularity under different operating speeds were analyzed. The results showed that flexible vibration of car body significantly affects sensitive wavelength of track geometric irregularity of high-speed railway; the most unfavorable wavelength and sensitive wavelength range of different types of track geometric irregularity are different under different operating speeds; there are 3 significant wave bands of sensitive wavelength of track geometric irregularity of high-speed railway, the sensitive wavelength within short wave range of 3-10 m is mainly related to flexible modes of car body, the sensitive wavelength within medium wave range of 10-60 m is mainly related to rigid body modes of bogie, and the sensitive wavelength within long wave range of 60-140 m is mainly related to rigid modes of car body.
