Study on Rail Vibration and Corrugation of New Rail Guard in Small Radius Curve
Publication: Resilience and Sustainable Transportation Systems
ABSTRACT
In order to further study the effect of vibration damping and anti-wear of a new rail guard system in the small radius curve section, the new rail guard and no-installation guardrail approximate routes for different speed of online testing, hammer test, and rail corrugation test are conducted. The tests show that with guard rail, the acceleration level of the vertical vibration decreased by 2.2 dB, while the lateral vibration reduced by 3.1 dB. When the train speed increased from 40 km/h to 55 km/h, the vibration acceleration of the rail also increased gradually in both the case with or without the rail guard. The transverse vibration can be reduced by 3.4 dB. At the same time, the rail corrugation is significantly reduced at the wavelength of about 50 mm. The test results show that the installation of new rail guard can restrain the rail vibration and slow the growth of rail corrugation.
