Cantilever crane vibration suppression method and device, engineering equipment and machine readable storage medium
The invention discloses a cantilever crane vibration suppression method and device, engineering equipment and a machine readable storage medium. Belongs to the technical field of engineering equipment. The method comprises the steps that a first operation function and a second operation function are determined based on a first operation signal of a first-level arm and a second operation signal of a second-level arm respectively, data reference is provided for determination of a first angular frequency, and the first angular frequency is determined based on the first operation function and the second operation function; whether high-frequency vibration exists or not is determined based on the preset high-frequency threshold value and the first angular frequency, the accuracy of high-frequency vibration recognition and judgment is improved, vibration suppression is carried out based on the second operation signal under the condition that it is determined that high-frequency vibration exists, through targeted online vibration suppression, the risk caused by double-frequency superposition vibration is greatly reduced, and the reliability of recognition and judgment of the high-frequency vibration is improved. Therefore, the vibration of the cantilever crane in the operation process of the engineering equipment is better inhibited, and the operation safety is improved.
