摘要：

In this paper the formulation used for numerical calculation of the natural frequencies and modes of an axisymmetric structure enclosing an acoustic cavity, essentially as a modification of an existing F.E. structural analysis, is described. The solution for the acoustic pressure in the cavity is obtained as a weighted residual approximation, resulting in only two extra equations to be added to the existing structural equations. The motivation for the exercise came from a desire to perform such an analysis for automobile tyres, where acoustic cavity effects are now known to be of practical consequence. © 1991.
