Vibration of Cylindrical Shells, with and Without Ring Stiffening.

Abstract

The dynamical response of two cylindrical shells, one with and one without ring-stiffening, was investigated. The driving-point admittance was measured and compared with predictions using the Mean-Value Admittance Method. This method predicts the geometric mean of the response of a vibrator with respect to frequency and is useful in understanding the behavior of many complex structures. The basic computations involve the mode functions, mode masses, and the mode density. The measurements were in good agreement with the theory, and demonstrate that the Mean-Value Admittance Method is a practical means of predicting the vibrational response of shell structures to point excitation.
