Abstract:The track irregularity power spectrum density of Beijing - Shanghai, Shanghai - Hangzhou and Shang hai- Nanjing High -speed railway was computed with Welch Periodogram method, and the characteristics of track irregularity was investigated from the perspective of wavelength and amplitude, meanwhile comprehensive exploration was made to analyze the causes. Then the coherence theory was adopted to analyze track irregularity and train vibration acceleration, and based on this, the train＇s detrimental wavelength caused by track irregularity was studied. The results show that high -speed railway lik
