  • Patent number: 5930155
    Abstract: A method of evaluating endurance of a vehicle wheel by computer simulation of a dynamic radial fatigue test. The modeling of the system is simplified by modeling the tire portion made of a nonlinear material by linear elements, and modeling each of the air pressure, the press-contact effect of the tire bead portion and the load applied through the contact between the tire and the drum is modeled as the direct load. With such a modeling, the stress applied to the vehicle wheel can be calculated by the linear analysis instead of the nonlinear analysis, and as a results thereof, the memory capacity and the calculation time are reduced.
