Predictions of dynamic-mechanical response of tire tread compounds

The dynamical-mechanical response of tire tread is a highly complex problem. The nonlinear nature of filled elastomers and the real-life working conditions of tires, such as various temperatures, high strains and frequencies, present significant challenges for testing and prediction. This presentation explores the results of dynamic mechanical analysis (DMA) tire tread formulations with a focus on dynamic strain sweeps. By varying individual ingredients in the formulation and their loadings, their impact and combined effect on storage and loss modulus are investigated. Based on obtained experimental data, existing models are used and compared to predict and simulate the storage and loss modulus of tire treads.
