Experimental Study of the Acoustic Cavity Resonance in Automobile Tire Dynamic Response

Abstract: A series of tests were conducted to measure the dynamic stiffness transfer functions between the wheel center of a rim-mounted tire and the contact patch. Of particular interest was the interaction between the tire acoustic cavity mode and the modes of the tire/rim system. By varying the concentration of helium gas within the tire, it was possible to sweep the acoustic resonance through a group of rim/tire resonances. These results showed that there is relatively weak interaction between the cavity modes and t… Show more
