Dynamic Smoothing Effect in Non-Linear Dynamic System under Polyharmonic External Excitation

Abstract:

The effect of the polyharmonic external excitation causes the emergence or onset of novel properties in the system. The article devoted into the oscillations induced in a rigid system by the polyharmonic external excitation. The analysis of the results obtained in this research confirms that the systems with the nonlinear elastic characteristics are rather sensitive to the changes introduced into the external excitation according to the law. Therefore, some assumptions, for instance, those concerning the monoharmonic nature of changes in the external excitation, which are commonly used in studying the real mechanical systems, are not always correct.
