摘要
In this research,the tire deformations due to rotation are divided into three parts:tread,belt and carcass.Tread deformation is obtained by using a rotating hollow cylinder model,belt expansion is calculated according to the laminated composite shell theory,and a formula of dynamic equilibrium profile is built to investigate carcass deformation.Moreover,a simple method is used to predict the footprint changes caused by tire deformation.Results show that a large deformation is occurring at tire shoulder,a smaller one at tread centre,and the shoulder deformations are mostly caused by carcass.Length of footprint side edges increase with tire rolling speed increasing.The predicted tread,belt,carcass deformations and footprint changes are in good agreement with finite element analysis results.The proposed method and the results will offer a helpful guidance to tire and vehicle engineers.
