It shows that the FE method of tireanalysis under driving state and the method dealing with large slip frictionalcontact problems are correct and reliable. The properties of tires under steady cornering state are studied with FEmethod and experiment. Based on the presented contact solution algorithm, a FEmethod is carried out to analyze the properties of tire under steady corneringstate via imposing slip-rolling-constraints on tire bead nodes which contact therim, and the modules are programmed. The mechanical properties anddeformation of tire under pure steady cornering state and steadycornering-driving state are analyzed, and the results show good agreement withthe experimental data.
