Modelling of quasistatic rolling of pneumatic tyre in Abaqus program complex

In the last ten years enterprises producing tyres for cars have had a tendency to the full automation that includes not only development of an independent line on tyre production, but also digital design based on the creation of a whole set of pneumatic tyres computer models with a series of calculations of their main characteristics at the car movement. Special attention is paid to the influence of the protector geometry, as well as the structure and properties of the materials of the tyre basic elements on its stress-strain state in the course of stationary rolling. To define these characteristics within the conditions of quasistatic rolling, the Abaqus program complex is used. The finite element modelling of a car tyre is carried out in the three-dimensional statement. The analysis of inflation and pressing is made both in the static state and during dynamic rolling. The results of modelling are epures of contact pressure distribution on the tyre surface.
