| Abstract(E) | This study proposes a simple method for estimating increase of tire/road noise due to acceleration torque from the rigidity of tread block. The validity of the method is examined for tires with different tread block rigidity which were prototyped by adopting different tread compounds. For the calculation of tread block rigidity, finite element analysis or an analytical model based on mechanics of materials is utilized, and the temperature dependency of rubber stiffness is considered. Indoor tire-alone drum tests are conducted to determine the increase of noise due to acceleration torque. The results reveal that a negative correlation can be confirmed between the increase of tire/road noise due to acceleration torque and the tread block rigidity. Thus, tread block rigidity can be a simple and useful parameter to estimate the increase of tire/road noise due to acceleration torque. |
