Abstract | The invention discloses a loader working vibration reduction control system and a fuzzy control method, and relates to the technical field of loaders. The system comprises a control unit, a lifting oil cylinder and a tipping bucket oil cylinder. The lifting oil cylinder and the tipping bucket oil cylinder are each provided with four oil ports, namely an oil inlet and an oil outlet of a rod cavity and an oil inlet and an oil outlet of a rodless cavity, and each oil port is connected with a high-speed switch valve used for controlling oil inflow or oil outflow of a rod cavity. The system further comprises an acceleration sensor, the acceleration sensor is used for detecting the direction and magnitude of the vibration acceleration of the whole loader and transmitting a detection signal to the control unit to form closed-loop feedback, and then the control unit adjusts the lifting oil cylinder to stretch out and draw back by controlling opening and closing of the high-speed switch valve to achieve vibration redu |
