| Abstract: | On the basis of the parametric minimum potential energy principle of contact problem, establishes the fi- nite element parametric quadratic programming solution of contact problem. As an example, the calculation of type RE_2 axle is carried out according to the 3-dimensional contact model, and some results are given. |
