Static analysis of different spoke structure of airless and conventional tyre

Abstract

An airless tyre is known as non-pneumatic tyres which are not advocated by air pressure. The major issues related to pneumatic tyre are puncture and flatness due to wear and tear, which lead to the development of airless tyres. The aim of this work is to conduct static analysis of airless tyre, considering various 3D printing materials with different spoke structures. The spoke structures like honeycomb, triangular and diamond and the 3D printing materials such as Acrylonitrile Butadiene Styrene + Polycarbonate (ABS+PC), Polyethylene Terephthalate (PET) and High Impact Polystyrene (HIPS) are considered for modelling of airless tyre. For conventional tyre, Neoprene rubber is considered. The static analysis is conducted using ANSYS workbench 19.2, and the total deformation, equivalent elastic strain, equivalent von-mises stress and strain energy are compared and evaluated for conventional and airless tyre.
