Tire–Pavement Interaction Simulation Based on Finite Element Model and Response Surface Methodology

Acquiring accurate tire–pavement interaction information is crucial for pavement mechanical analysis and maintenance. This paper combines the tire finite element model (FEM) response surface methodology (RSM) to obtain analyze structure under different loading conditions. A set of experiments was initially designed through Box–Behnken design (BBD) method input output variables RSM calibration. The resultant evaluated accurately using variance (ANOVA) approach. Then, simulations were conducted magnitudes static optimal parameter combination obtained from RSM. results show that deviations between real test mostly below 5%, validating effectiveness FEM. Additionally, three dynamic conditions—including free rolling, full brake, traction—were simulated by altering rolling angle translational velocities. Finally, conditions analyzed based on contact feature.
