Vibration of Train-Rail-Bridge Interaction Considering Rail Irregularity with Arbitrary Wavelength
A generation method for the rail random irregularity with arbitrary wavelength interval (WI) is developed, and its accuracy and efficiency are demonstrated. Then a moving wheel-rail-bridge interaction element is derived to establish the finite element equations of motion for the train-rail-bridge interaction system, and the flow chart of assembly and calculation for the system equations is give...
متن کاملAnalytical Approach to Vibration Analysis Of the Wheel-rail contact
Wheel/rail contact simulation is one of the most complicated problems in the modeling of railway vehicles. The wheel/rail interaction plays a unique role in rail vehicle dynamics. In this paper, the dynamic response of the wheel on irregular rail track is analyzed with analytical approach using the method of Multiple Scales (MMS). The Hertzian contact theory is used to obtain the relationshi...
متن کاملEstimation of track parameters and wheel–rail combined roughness from rail vibration
Rolling noise from railways is significantly affected by the wheel–rail combined roughness and the dynamic properties of the track. To facilitate vibration and noise predictions it is desirable to be able to determine these parameters accurately from field measurements. In this study an inverse method to determine these parameters is adopted and enhanced. Use is made of a track model based on a...
متن کاملImpacts of Wheel–rail at Railway Turnouts
Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh-
Timoshenko beam elements. The ra...
