Abstract

An experimental investigation of the nonlinear vibrations of cylindrical shells was undertaken. An aluminum shell was vibrated by means of an induction shaker. An optical device was used to obtain radial displacement measurements. Several modes of vibration were studied in detail. Various nonlinear effects were observed. These included nonlinearity in the driven mode frequency response curve, the participation of the companion mode, and the participation of axisymmetric response at twice the driven frequency. The experimental results indicated only a softening type nonlinearity. The response of the companion mode was significant in several of the modes studied and was of a more complex nature than was predicted by previous theoretical work.
