© 2018, Chulalongkorn University. All rights reserved. The rubber solid tire was built using three different compound layers. In order to develop solid tire, the finite element method (FEM) was employed to model and analyze its performance. The constitutive model was important to describe the simulated results of FEM; therefore, the hyperelastic material models were implemented for each compound of solid tire layers. The second order Ogden model was the most agreement with the compression test of the rubber compound specimens. The R2 of internal, middle and tread compound layer was 0.990, 0.988 and 0.989, respectively. The solid tire model was developed and tested with the compressive loads. Particularly, the compressive loads on the solid tire were performed with the experiment regarding to the simulation. The solid tire model which was complied with the Ogden model had good agreements with the experimental results. It had an average error less than 8.49%. The Ogden model which was implemented with the mechanical property of rubber compound of solid tire was found that it would be advantageous to design and develop the novel solid tire in the future work.
