Accurate material modeling is essential for capturing the viscoelastic behavior and large deformations of tires under dynamic conditions. Because hydroplaning performance is highly sensitive to rubber properties, this study focuses on improving simulation accuracy through implementation of advanced material models. Viscoelastic properties of tread compounds were characterized using Dynamic Mechanical Analysis (DMA) and incorporated into SOL700-based hydroplaning simulations. A comparative study was performed between conventional hyperelastic models and visco-hyperelastic models to evaluate their predictive capabilities. The simulation results were validated against experimental data, demonstrating that incorporating viscoelastic properties significantly enhances the agreement between numerical predictions and real-world behavior. This approach provides a more reliable framework for virtual tire performance evaluation. |
