Abstract
In the first report, a study of dynamic contact patch measurement technology was presented and contact behavior in terms of dynamic adhesive & slippage regions for improving eco-tire’s cornering power/force was described. However, since the proposed methodology visualizes global contact stress distributions by averaging a number of measurement signals, the effects of a complicated tread pattern design represented by lug grooves, sipes, and so on tend to be mitigated. In order for taking these effects into account, the measurement and visualization methodology of detailed tread pattern behavior in a contact patch has been developed. As its application, the new tread pattern design of the latest eco-tire for the improvement of compatibility between braking performance and low rolling resistance has been proposed and verified.
