To the question of non-harmonic force oscillations and moment by the vibration generator

Abstract

In the article, a vibration exciter is considered, containing four unbalances rotating around parallel axes, the axis of rotation of which are located on a common base, rigidly connected with the working body. The imbalances rotate uniformly and in pairs have the same angular velocity in the opposite direction. The conditions are formulated to ensure excitation of a rectilinearly oscillating force and rotation conditions by the vibration exciter. The purpose of the created dibaleans is to inform the working body of the machine of non-harmonic oscillations. The dependence of the force excited by the vibration exciter on the angle of rotation of the unbalance is determined. As a result of the studies, it was found that a centrifugal vibration exciter with four unbalances rotating in pairs with the same angular velocities can be used depending on the mutual phasing of the unbalances to excite non-harmonic oscillations of either force or moment.
