Title Vibrations of a Piston Pin with Eccentric Center of Gravity
Author(s) M.M. Sorochkin (Unmanned Helicopter Design Office, Israel, marksoroch@gmail.com)
Abstract Combustion pressure boost in the cylinder of modern diesel engines increases the loads acting on the piston pin bearings and lubrication of the piston pin bearings becomes a serious problem. Using a piston pin with an eccentric center of gravity solves this problem. This article deals with the phenomenon of parametric resonant oscillations of the piston pin during the reciprocating motion of the piston. The purpose of the study is to use a phenomenon that increases the amplitude of the oscillations and, consequently, the sliding speed in the relative rotational movement of the piston pin.
Keywords parametric resonance, oscillation amplitude, resonance zone, piston pin
