Highly Directional Design of Planetary Vibratory Exciter and Its Kinematic Analysis

Abstract

Development of new techniques of controlled excitation for directed vibrations is actual engineering problem. The paper analyses properties of new design of vibratory exciter with highly directed force to be produced. The key feature of the generator is partially rotating planetary gear as a source of directed inertial force. The mechanical principle of force generation is based on composition of rotation motions of unbalanced massive body driven by the crank of special type. Use of this principle of mechanical drive allows to vary produced force and increase energy efficiency of the device. Kinematic properties of the generator are analyzed in the article and further applications of the device are recommended as well. The graphic presentation of time and directional behavior of produced force illustrates work regime of the exciter. The article also suggests new analytic characteristics which describe efficiency of vibration exciters in general.
