Discretized Standing Waves Tire Model 2009-01-0066
A new tire modeling method, called the discretized standing-wave tire (DST) model method, is described. It is based on an assumption that the modes obtained with our modal analysis method are standing waves. This method regards the tread surface as uniformly continuous in the circumferential direction. Our DST model is also used to conduct a prediction analysis of the transmissibility of the suspension, and the results are compared with experimental data to validate the model. The experimental and predicted results are compared for situations where two different types of tires are mounted on a double-wishbone front suspension to demonstrate the prediction accuracy of the DST model.
