FEM TIRE DESIGN AND ANALYSIS OF DURABILITY

Finite Element (FE) tire models are increasingly being used for tire design, studies of vehicle design and dynamic research. These tire models have the inherent advantage of being able to cover a wide range of variables in tire design (such as precise tire configuration and material composition) in addition to a wide range of operating conditions (such as tire load, inflation rate and driving speed). It is also possible to consider a variety of road data disruptions. This paper provides a finite element commercial code for use in the development of new tire designs and vehicle dynamics simulation. Rolling tire output responses such as lateral forces and self-aligning moment produced during vehicle maneuvering due to steering input and vibration responses to road disturbances are of particular interest. The model will also be applicable to investigate other issues related to tire design, such as the heat generated in the rolling tire carcass. This may pose particular issues during take-off in heavily loaded tires, such as aircraft tires. This model would make it possible to quickly develop new tire designs to meet specific requirements. A more precise model of rebar layer was developed for composite material such as ply and belt. To order to determine the amount of wear, wear depth and wear mass are added.
