The last few years have shown progress in finite-element analysis intended for use by design engineers. Many programs that work with CAD provide several different types of analysis, and the range of ...

A wealth of practical cases indicates that the fatigue failure of subway bogies primarily stems from the modal resonance of the structure. If the modal characteristics of the entire vehicle, including ...

This study examines the problem of inadequate dynamic stiffness at the connection points of car bodies. A method based on modal contribution analysis to assess whether the cause of inadequate dynamic ...
