Abstract
A revolution vibration suppressing method and apparatus for pump truck boom is provided. Vibration severity of the boom in the revolution direction is detected. Dynamic characteristic parameters of the boom are extracted. A control signal that can be used to control the revolving actuator to compensate the vibration severity according to the vibration severity and the dynamic characteristic parameters is calculated. The revolving actuator is driven according to the control signal to move, to suppress the revolution vibration of the boom. A revolution vibration suppression controller and a revolution vibration suppression device for a pump truck boom are provided to implement the methods. With the disclosed methods and apparatus, the vibration of a pump truck boom in the revolution direction can be suppressed, and therefore the risk of failures of the boom is decreased and the operating safety in the work is improved.
