内容記述 | In the present paper, the impact response in the field test on the railway jointed track is simulated using the wheel-track vibration model with the finite element method. The simulated results on the dynamic response are discussed in terms of railpad force, sleeper-ballast interaction force, sleeper acceleration and ballast acceleration. The ballast and substrate are modeled as 2D elastodynamic bodies. The accuracy of the vibration model is investigated based on the comparison with in-situ measurements. In the railpad force and the sleeper-ballast interaction force, the impact responses are accurately simulated; the post-impact responses obtained by the present model have the differences in terms of period and amplitude in contrast to the measurements. The sleeper acceleration has the different peaks in the spectral space between the numerical results and the measurements; the intensity of the response shows good agreement in the frequency range under 200Hz. The ballast layer is an assemblage of crushed hard stone, of which the particle action influences to the macroscopic dynamic response of the ballast layer. Therefore, though the present model can evaluate the maximal acceleration level, it may simulate the spectrum distribution sufficiently. | |||||
