Abstract
The paper deals with low-frequency vibration of a vibroprotection system consisting of a heavy ball with an air damper in an inverted-pendulum spherical socket under the action of external harmonic excitation. The ball in the spherical socket rolls without sliding and is a working body of the ball-type absorber of the inverted-pendulum forced oscillation. Dynamic equations for joint motions of the heavy ball and the inverted pendulum are formulated and analyzed. The authors have obtained amplitude-frequency characteristics of the absolute deviation of the inverted pendulum upper point and the relative displacement of the ball in the spherical socket. A new procedure for the determination of setting parameters for a ball-type oscillation absorber is proposed.
