Numerical investigation of tire standing wave using 3-D patterned tire model

The tire standing wave is one of the crucial factors that may lead to unexpected tire structural failure because the total strain energy of the tire dramatically increases when it occurs. However, its analytical analysis has been limited owing not only to the complicated tire structure and material composition, but also to the problem nonlinearity. In this paper, its characteristics are numerically investigated with the help of the transient dynamic rolling analysis of the 3-D patterned tire model. The numerical reliability is assessed with the comparison of critical speeds with the experimental results and those obtained with the simple tire model. Also, the effects of the tire inflation pressure and the vertical load on the critical speed are parametrically investigated.
