Embodiment Construction

[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] The boom of construction machinery can extend the working surface through the extension of the boom section, and can be used in construction areas that are not suitable for personnel to enter. In order to expand the construction area and facilitate operation and movement, a turntable connected to the jib is usually provided at the bottom of the jib. The boom is usually composed of 3-6 boom sections, each boom section is connected in sequence (for example, hinged), and each boom section is provided with a boom section oil cylinder, by controlling the extension of the boom section oil cylinder corresponding to each section The movement of the boom section ...

Abstract

The invention discloses a method, a device and a system for controlling vibration of an arm rest and an engineering machine with the arm rest. The method for controlling the vibration of the arm rest comprises the following steps of: receiving arm section state signals for representing the states of at least one section of arm rest in real time; extracting corresponding dynamic property parameters from a dynamic property parameter database (128) in which dynamic property parameters of the arm sections are stored according to the received arm section state signals; calculating to obtain arm section control parameters according to the arm section state signals and the extracted dynamic property parameters; and outputting arm section control signals of at least one section of arm section according to the arm section control parameters. By the provided method for controlling the vibration, one or more arm sections of the arm rest can be monitored in real time, and the arm section control parameters can be calculated according to the arm section state signals and the extracted dynamic property parameters to generate the arm section control signals of one or more arm sections, so that the vibration of the whole arm rest can be controlled accurately.

Description

technical field [0001] The invention relates to the field of construction machinery, and in particular, relates to a vibration control method for a boom, a vibration control device for a boom, a vibration control system for a boom, and construction machinery with a boom. Background technique [0002] Construction machinery with boom structure is a commonly used mechanical equipment. The service life and maintenance cost of its boom are not only limited by production and manufacturing quality, but more seriously by working intensity and vibration. Especially the vibration during work will have a continuous impact on the jib, reduce the mechanical properties of the jib, and reduce the fatigue life of the jib, and this damage is not easy to find. In severe cases, it will affect the quality of use and even endanger construction safety. Therefore, in the use of such construction machinery with a jib structure, the vibration control of the jib is very important. [0003] There a...
