Dynamics of a body vibrating according to the law of harmonics on an air-cushion

Abstract

Vibrations of a part on a compressible and in-compressible air-cushion vibrating at harmonical fre-quency are analysed and applied to automatic assembling. The equations of pressure distribution in air-cushion be-tween the part and the supporting track surface are given. To solve them a finite elements model is set up. The pressure distribution equations are co-solved with the equation of motion of the part based on air-cushion vibrating ac-cording to harmonic law. The areas of the parameter com-binations of air supply and part excitation are determined at constant amplitude vibrations, at slightly and strongly modulated vibrations, at abruptly changing amplitude vi-brations and beating. The dependences of part vibrations amplitudes, beating period on frequency and amplitude of track excitation and air blow parameters are determined.
