Static Contact Characteristics Analysis of Wide Base Tire against Hot Asphalt Pavement

In order to analyze mechanism of pneumatic tire rollers compacting against hot asphalt pavement, taking the process of wide base tire of rollers compacting against hot asphalt pavement as research object, the wide base tire is loaded up with inflation pressure and axial force to study the contact characteristics. Two finite element contact models are established by ANSYS, one of which is for the contact of wide base tire against rigid pavement, and the other is for the contact of wide base tire against hot asphalt pavement. The static contact characteristics of wide base tire against hot asphalt pavement are achieved though FEA method, including whole deformation of tire, formation variation of contact patch, and stress distribution of contact area.
