A Study on the Correlation Between Measured Track Irregularities and Vehicle Responses in High-Speed Lines

In this study, a correlation analysis is conducted between measured track irregularities and vehicle responses. For this purpose, four track irregularity types, namely track gauge, longitudinal level, super-elevation and track alignment, and the vertical/lateral acceleration of carbody are recorded using high-speed comprehensive inspection train. The results indicates that vertical carbody acceleration is dominated by the irregularity of longitudinal level, and can be affected by the irregularity of super-elevation (with the wavelengths above 50 m). The lateral carbody acceleration is largely influenced by the irregularity of track alignment (with the wavelength above 30 m) and super-elevation (with the wavelength above 10 m). Yet, vehicle responses are seldom influenced by the irregularity of track gauge. Using transfer function, VCA can be well predicted at the wavelengths above 10 m, and LCA can be well predicted at the wavelengths above 50 m.
