| 摘 要： | A kind of improved contact frictional model on basis of traditional Coulomb Friction model is adopted.Corresponding contact element is also given. The contact algorithm on basis of augmented Lagrange method is introducedand successfully applied to complex contact friction problem. Test example and actual engineering case all show that thealgorithm of the model is efficient and computation results agree well with general rules.
