| Abstract: | Analyses the wheel rail contact problem with the three dimension finite element parametric quadric program and provides a new method of studying the wheel rail ralationship. Gives the computation results of the contact innet force within the wheel rail contact region. And also points the contact state and stress distribution of each pair of contact points are also pointed out. |
