【Abstract】 Causes of the chatter of temper mill were researched from the aspect of electromechanical coupling of complex electromechanical system. Combining the features of CM04 temper mill’s electrical driving sistem and its working status, the paper mainly studied how the harmonic current of electrical driving system affects the motion of temper mill. It has been confirmed that the influence of harmonic current is one of the causes of chatter of the temper mill system. Adjusting parameters of filter and controlling system will weaken and eliminate the vibration.[更多还原
