โœฆ Synopsis


The author investigates the problem of the existence and properties of bounded oscillations of a quasilinear system of the saddle type in the presence of a rapidly changing external force*. The obtained results generalize a theorem of Farnell. Langenhop and Levinson.

The author expresses his gratitude to V.V. Nemytskii in whose seminar the preliminary results of this work were presented.

An inverse non-linear force vibration problem based on the iterative regularization method, i.e., the conjugate gradient method (CGM), is used to estimate the unknown time-dependent external forces in a damped system having time-dependent system parameters by using the measured system displacement.

When a simple harmonic oscillator is subjected to a sinusoidally varying external force whose frequency is different from the natural frequency of the oscillator, there is a simple and well-known phase relation between the purely forced response and the forcing function. They will have the same or
