Considerations on the Excitation Mechanism of the Vertical Vibration Symmetrical and Antisymmetrical Modes in Railway Vehicles
نویسنده
چکیده
The railway vehicles are complex oscillator systems featuring specific vibration characteristics. The symmetrical and antisymmetrical vibration modes represent a property of the railway vehicle vibrations, due to its symmetry in construction. The paper describes the excitation mechanism of the symmetrical and antisymmetrical modes in a vertical plan of a railway vehicle on a track with irregularities. The symmetrical and antisymmetrical modes of the axles, as well as the vibration modes of the vehicle, are focused on by an appropriate processing the vehicle movement equations.

Exploring Biodynamic Response (Apparent Masses) of a Seated Human Body Exposed To External Excitation in Vertical Direction
In the present work, the biodynamic response behavior of seated human body subject to vibration in vertical direction have been extensively examined. The biodynamic response parameter of seated human body have been analyzed in terms of apparent masss (AM).The AM describe “to –the -body”force motion relationship at the interface of huma and seat. The present work proposed the six degrees of free...
متن کاملWheelset Condition Monitoring based on pass-by vibration signals
Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...
