Abstract

The invention relates to the technical field of arm support type engineering machinery and particularly discloses a method for inhibiting the vibration of an arm support. The method comprises the following steps of: a step A of detecting an amplitude A, a phase & and a period T of the vibration of the tail end of a tail section of arm support in real time; a step B of comparing the amplitude A with a preset value, entering a step C if the amplitude A is greater than the preset value, and finishing if the amplitude A is less than the preset value; and the step C of driving an arm support oil cylinder on at least one section of arm support to act, so that a motion component with an amplitude A1, a phase &1 and the period T is generated at the tail end of the tail section of arm support, wherein a difference value of the amplitude A1 to the amplitude A is less than a preset difference value, a difference value of the phase &1 to the phase & is nT / 2, and n is an odd number. The invention also discloses a system for inhibiting the vibration of the arm support and the arm support type engineering machinery with the same.

Description

technical field [0001] The invention relates to the technical field of boom type engineering machinery, in particular to a method for suppressing boom vibration. The 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 basic construction sites, especially for large-scale construction sites, which can greatly reduce the heavy physical strength of concrete transport on construction sites. Labor, improve construction progress and work efficiency. [0003] The concrete pump truck is an efficient concrete conveying equipment that integrates the concrete pumping mechanism, the boom system, the supporting mechanism, etc. on the chassis of the car, and integrates driving, pumping, and material distribution. The boom system is the support a...
