JIB VIBRATION SUPPRESSION METHOD, SYSTEM AND JIB-TYPE ENGINEERING MACHINE

摘要

A jib vibration suppression method, a jib vibration suppression system and a jib-type engineering machine having the jib vibration suppression system. The jib vibration suppression method comprises the following steps of: step A, detecting the amplitude A and frequency f of vibration at an end of a tail section of a jib in real time; and step B, driving a jib cylinder on at least one section of the jib to operate, so that the end of the tail section of the jib generates a movement component having the amplitude A1 and frequency f1, the amplitude A1 being less than the amplitude A, and the frequency f1 being greater than the frequency f.
