Abstract

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.

Description

technical field [0001] The invention relates to the technical field of boom type construction machinery, in particular to a vibration suppression method of a boom. The present invention also relates to a boom vibration suppression system and a boom type construction machine with the boom vibration suppression system. Background technique [0002] Concrete pump truck is a common boom-type construction machinery. Concrete pump truck is widely used to transport concrete on capital construction sites, especially for large-scale construction sites, which can greatly reduce the heavy physical effort of concrete transport on construction sites. labor, improve construction progress and work efficiency. [0003] Concrete pump truck is a high-efficiency concrete conveying equipment that integrates concrete pumping mechanism, boom system, support mechanism, etc. on the chassis of the vehicle, integrating driving, pumping and distributing. The boom system is the support and motion car...
