An amplifier of mechanical oscillations
Abstract
It is shown that an electromagnetically or electrodynamically driven system provided with a self-oscillating circuit possesses the properties of a mechanical-vibration amplifier. Relations are derived which describe the characteristics of amplifiers suitable for use in systems intended for exciting variable loads in fatigue testing and similar facilities.
