Abstract

The finite element model of a ballasted track system was established in order to study the coupling effect between adjacent wheel sets. The research results indicate that due to the coupling effect between adjacent wheel sets the train loads should be treated as a series of loads from each bogie rather than from separated wheel sets. This coupling effect influences the stress of the ballasted track system seriously and when the coupling effect between adjacent wheel sets increases, the stresses of the ballasted track system rise obviously. Meanwhile, the stress distribution is also changed from “M” shape to inverse “U” shape gradually. Besides that,the simulation results point out the coupling degree becomes strong with the increased number of wheel sets and the decreased number of axle base. In terms of the common railway vehicles, due to the shorter axle base, the coupling degree between adjacent wheel sets is stronger for freight vehicles than for passenger vehicles. And in terms of the multiaxle bogie, the coupling degree increases not any more, when the number of wheel sets increases more than three.
