Dynamics Analysis And Experiment Research of Torsional Vibration for YJC Redactor-electronic Motor System

The rapidly rotated input-shaft of YJC redactor-electronic motor system often induces torsion with the change of load,which destroy the system,so it is very important to analyze the torsional vibration model of this shaft.This paper makes a concentrated quality dynamic model of YJC single stage redactor system,taking the simple harmonic excitation as an example,deduces the forced vibration equation of the electronic motor's output-shaft in theory,and analyzes the fundamental mode simply,these offer proof for checking malfunctions of the system.The vibration equation is proved right by the experiment and may be refered by other YCJ redactor system.
