Investigating the rolling resistance of Radial Cargo Tire using the finite element method and Taguchi

In the design of radial and bus tires, the examination of various components of truck radial tire for achieving desirable properties such as strength, wear, noise and rolling resistance to optimize the tire are important. In this article, the influence of various parameters such as tread depth, wire strength, number of wires, belt width, and apex type on the rolling resistance is numerically investigated by using finite element software (ABAQUS). In order to simulate the belts and their angles, the Rebar model is used. Due to large deformations in the tire, non-linear boundary conditions at the tire-road contact boundary and hyper-elastic and viscoelastic behaviors of the rubbers, the considered model will include non-linear deformations. By using the method of experimental design and Taguchi, the optimized tire structure optimization is achieved in order to minimize the rolling resistance.
