タイヤ振動特性がタイヤ／路面騒音に及ぼす影響に関する研究

（タイヤ押付力が音圧特性に及ぼす影響）

抄録

In recent years, the noise of the engine and the intake and exhaust systems has decreased due to the improvement of vehicle performance, and the contribution of tire/road noise has increased relatively. There are two types of sound sources for tire/load noise, one relating to air resonance system and the other relating to the vibration system of structure. It is considered that the noise caused by tire vibration due to road surface in a low frequency band is affected by tire vibration characteristic. The purpose of this study is to clarify the effect of tire vibration characteristic on tire/road noise. In this study, the sound pressure characteristics were examined with the two tire preload condition and the effect of tire preload on sound pressure characteristics were investigated.
