Computer Simulation and Experimental Study of Vertical Deformation in a Radial Tire under Static Load Using Finite Element Method

This research work is devoted to the simulation of a steel-belted radial tire under static load. The nonlinear finite element calculations were performed using the MSC.MARC code installed on a computer system equipped with a parallel processing technology. Hybrid elements in conjunction with two hyper-elastic models, namely Marlow and Yeoh, and rebar layer implemented in surface elements were used for the modeling of rubbery and reinforcing parts, respectively. Two-dimensional axisymmetric elements were used for the modeling of rim-mounting and inflation and three-dimensional models were developed for the application of the radial load. Based on the results of the load deflection (displacement) data, the tire stiffness under radial load was calculated and compared with their corresponding experimentally measured value. The comparison verified the accuracy of the measured radial stiffness
