Analytical 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...

Rail System Noise and Vibration Control

Control of noise and vibration emitted by steel wheel and rail transportation systems has a long history of designs and techniques, some of which were dismal failures and some which worked very well. Many of the early efforts had a valid technical base for the design, however, there were also many based on intuition or ideas with great expectations, but which had no real technical basis. In the...

How to Park Freight Trains on Rail-Rail Transshipment Yards: The Train Location Problem

In modern rail-rail transshipment yards huge gantry cranes spanning all railway tracks allow for an e cient transshipment of containers between di erent freight trains. This way, multiple trains loaded with cargo for varying destinations can be consolidated to a reduced number of homogeneous trains, which is an essential requirement of hub-and-spoke railway systems. An important problem during ...

Estimation 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...

Causal Analysis of Passenger Train Accidents on Freight Rail Corridors

A number of economic, technical and political factors have limited the development of new, dedicated, very-high-speed rail systems in North America. Consequently, most, near-term development of improved or expanded passenger rail service in the U.S. will involve use of existing railroad infrastructure or rights of way. Comprehensive understanding of train accidents on shared-use corridors is cr...
