Abstract

The vibration characteristic of tire is heavily related to the noise and comfort on driving. Therefore, in this paper, we investigate modal charateristic of non-pneumatic tires with Honeycomb spokes. The modal analysis of non-pneumatic tire is investigated for geometric of non-pneumatic tire(NPT) which is designed according to the cell angle of honeycomb cell. Investigation of natural frequencies and mode shapes of non-pneumatic tire are compared regular type NPT with auxetic type NPT. The analysis is based on the finite element method and used ABAQUS program which is able to analyze of non-linear. The material of NPT is used for the Ogden energy model which is model of hyperelastic material. As a result, natural frequencies and mode shapes of non-pneumatic tires with honeycomb spokes are affected by the angle of honeycomb cell.
