Static Analysis of Tyre Model developed from Natural Rubber Vulcanizates

This paper is on the static analysis of a tyre model developed from Natural Rubber vulcanizates using ANSYS Workbench 14.0 software. The pristine kaolin used as filler material in the Natural Rubber vulcanizates was oleo chemically modified from Rubber Seed Oils (Heveabrasiliensis) by intercalation which was achieved in the presence of hydrazine hydrate as co-intercalate. A typical P195/55 R16 85H tyre model was developed and the factors describing the linear isotropic elastic behaviour of rubber vulcanizates were established. The Finite Element Analysis was developed on maximum inflation pressure of 0.2206 MPa and maximum load capacity of 515kg obtained from the tyre size specification load index. The results obtained from the study show that the tyre material developed from Natural Rubber/Organomodified kaolin will perform well under static structural analysis, as the von Mises stress value of 1.0105MPa obtained on maximum inflation is lower than the applied maximum inflation pressure of 0.2206 MPa and the von Mises stress value of 0.9448 MPa obtained on application of vertical load of 5.15kN is lower than the specified pressure on vertical loading.
