Ballasted tracks are among the most widespread railway track typologies. The ballast
possesses multiple functions. Among them, it significantly affects the dynamic interaction …

A study regarding the safety against crosswinds of a high-speed train running over a railway
bridge belonging to the future high-speed railway network in Russia is presented. The …

An innovative stochastic dynamic model of a 3D train-track-bridge coupled system (TTBS)
with refined wheel/rail interaction is established for a high-speed railway based on the …

European design standards have established an upper limit on the deck acceleration of the
high-speed railway bridges, however the influence of local vibrations of the deck members is …

In this paper, the multi-time-step method (MTS) of time integration is proposed to reduce the
computational cost of solving the dynamic interaction of a train-track-bridge coupled system …

A closed-form solution is presented for the dynamic response of a two-axle asymmetric
vehicle moving over bridges, along with potential applications highlighted. First, by modeling …

Based on the random theory of the probability density evolution method (PDEM), a refined
random wheel/rail contact model for train-track-bridge systems is proposed. The trace line …

This paper addresses the reliability analysis of high-speed railway bridges with stochastic
methods to account for uncertainties in the mechanical model. The emphasis is on ballasted …

In this paper, the dynamic response of an Euler-Bernoulli beam with general boundary
conditions (BCs) and subject to a moving oscillator is examined. Notably, novel approximate …

A novel vehicle model is proposed to scan bridge frequencies effectively by incorporating
both the size of wheel and the unsprung mass in the formulation of an vehicle–bridge …
