Title:
BOOM VIBRATION CONTROL DEVICE, METHOD, SYSTEM AND CONSTRUCTION MACHINERY
Document Type and Number:
WIPO Patent Application WO/2015/085954
Kind Code:
A1
Abstract:
A boom vibration control device, method, system and construction machinery, the control device comprising a receiving apparatus (100) and a control apparatus (200); the receiving apparatus (100) is used for receiving the current boom vibration intensity and the current valve core displacement of a control valve (5); the control apparatus (200) is used for adjusting the control current of the control valve (5) on the basis of the difference between the valve core displacement of the control valve (5) corresponding to the current boom vibration intensity and the current core displacement of the control valve (5), and thereby controlling the boom vibration; the control valve (5) is positioned between an oil source and a boom oil cylinder (3), and controls the movement of the boom oil cylinder (3) by means of the control current. The present device improves the precision of vibration control.
