Abstract

High-accuracy tire models are needed to represent road surface inputs when conducting analyses of vehicle behavior and vibration. A new tire modeling method, called the discretized standing-wave tire (DST) model, is also described. It is based on the assumption that the modes obtained with our modal analysis method are standing waves. This method regards the tread surface as a uniform continuum in the circumferential direction. Our DST model is also used to conduct a prediction analysis of road noise.
