Oscilações de relaxação e suas aplicações - I

Abstract

Relaxation oscillations are maintained by a constant external influence and present two different timescales (fast and slow). They have properties different from the pendular oscillations which, for small amplitudes, reduce to harmonic oscillations. In this first paper we present the differences between relaxation and pendular oscillations, showing illustrative examples of application of relaxation oscillations in a mechanical system (Tantal vase) and an electric circuit. © The Sociedade Brasileira de Física.
