Three Dimensional And Nonlinear Finite Element Analysis And Performance Simulation Study For Radial Tire

With the development of the automobile industry, the study on high performance tire is becoming an active research field attracting researchers all over the world. Produce and use of radial tires to replace other tires is the development direction of the tire industry in our country. It is one of the main projects of the 9th National Five-Year-Plan of China to provide advanced technology for design and manufacture of high performance radial tires. The study of high performance radial tires would bring on significant economic as well as social benefits. Moreover, it makes the tire research to be an area full of challenge that the research is closely related to many subjects such as science of material, mechanics and mechanical engineering, etc, and especially that the materials used for tire, the large deformation of tire and the contact between tire and road are all dealings with strong nonlinearity.In this paper, the development history of the tire design theory is summarized, especially the tire design theories based on FEM and developed the past 10 years are emphasized.Up to 11 materials in 3 sorts categories used in the car tire have been tested for their physical properties and then the proper constitutive law of each material is selected for modeling.In the CAD for tire structure design, a new digital method for drawing the contour of a tire is developed in this paper, which makes the drawing of tire contour more freely than...
