Results are produced using the improved Fourier-series approach to investigate the effects of wheel speeds, roughness wavelengths and interactions between multiple wheels on wheel/rail contact forces.
Then more complicated models are developed and used to investigate the effects of multiple wheels on a rail.
Virtually multiple wheels are defined as wheels that provide multiple manipulation positions for scrolling by the finger.
The presence of multiple wheels on the rail leads to reflections of waves in the rail.
This is not the case in practice, where multiple wheels roll on the rail.
The paper explores such effects on the rail vibration caused by multiple wheels acting as supplementary dynamic systems.
The vertical interaction between a train and the track is calculated as a time history for single or multiple wheels moving on periodically supported rails, using a wavenumber-based approach.
In this paper, the Fourier-series approach is employed to study wheel rail interactions generated by a single, or multiple wheels moving at a constant speed along a railway track.
The SIMbot (for spherical induction motor) is still very much a lab-bound experiment, but its omnidirectional motion and sophisticated yet elegant control mechanisms are likely a source of envy to robots that use legs or multiple wheels to get around.
In order to investigate the influence of different track structures on the vibration and structure-borne noise of ECBGs, a frequency-domain theoretical model of vehicle-track coupled system, taking into account the effect of multiple wheels, is firstly established in the present work.
