Finite element simulation for air leak of rolling radial tire

Taken the contacts of tire-rim and tire-road into account,an axisymmetric and a three-dimensional finite element tire models with the aid of ABAQUS code are constructed in the present study.Firstly,using the axisymmetric model,the rim is mounted in the tire,along with the tire being inflated.Secondly,in order to reduce the cost of calculation,with the help of the advanced method of axisymmetric model to three-dimensional model,the problems of tire-pavement contact and the air leak of rolling tire with low velocity are analyzed.The distribution of contact pressure at tire-road interface is presented,and the deformation configures of the air leak tire at different times are also given.Furthermore,the relationship between the sinkage of tire and the time of air leak are predicted.
