Abstract
Methods for study of the transition process of induced vibrations in a cylindrical shell under a local disturbing load whose amplitude and frequency vary in accordance with given laws are developed. The amplitudes of certain vibration modes are compared with those in the transition process under a disturbing load with a constant frequency and amplitude as well as under steady vibrations. It is confirmed that, to determine the maximum amplitudes of total shell deflection, it is sufficient to consider only the vibration modes whose natural frequencies are lower than the frequencies of the disturbing load.
