The vibration response of a spring-mass-damper system with a parametrically excited pendulum hinged to the mass is investigated using the harmonic balance method. The approximate results are found to be fairly consistent with those obtained by the numerical calculation. The vibrating regions of the

β¦ Synopsis
The dynamics of a vibration machine with piecewise linear elastic ties under parametric harmonic excitation is investigated. Di!erent designs of elastic elements with periodically time-varying elasticity are described. Speci"c non-linear features of parametric oscillations in the system under study are revealed (the invariance of parametric vibration regime to possible disturbance of phase co-ordinates, conditions of limitedness of amplitude of parametric vibrations, spectral features of non-linear parametric regimes, etc.). By the utilization of these non-linear e!ects, a procedure for the design of the main parameters of a parametric vibromachine is proposed.

The global bifurcations and chaotic dynamics of a parametrically excited, simply supported rectangular thin plate are analyzed. The formulas of the thin plate are derived by von Karman-type equation and Galerkin's approach. The method of multiple scales is used to obtain the averaged equations. Base
In this paper a variational formulation of optimization problems for mechanical elements like bars or plates, subjected to a parametric excitation force, periodic in time is given. Objective functions characterizing the parametric resonance are introduced. The paper deals with the problem of "nding
The parametric instability of a beam under electromagnetic excitation was investigated experimentally and analytically. In experiment an electromagnetic device, acting like a spring with alternating sti!ness, was designed to parametrically excite the beam. The frequency and the amplitude of the exci
