Abstract: Non-pneumatic tyres (NPTs) have wide application prospects due to their advantages of no run-flat, no need for air pressure maintenance and no risk of tyre explosion. This project compares the behavior of the following spoke designs : hexagonal, radial, angled and triangular. After selection of the optimal design DOE analysis is done on the spoke design to find an optimal spoke shape which has stiffness similar to that of a pneumatic tyre. The paper discusses the effect of uniaxial loading in static conditions and vibrational analysis of various geometric shapes of spokes in NPT. The spoke structures are designed using Solidworks CAD software and analysis is done using ANSYS. The DOE analysis is done using Minitab software. The expected outcome of the project is the identification of optimal spoke structure for NPT to be used in LMVs at high speeds.

Keywords: NPT, spoke structure, CAD, Finite Element Analysis, DOE.
