    Abstract
  • Aiming at the problems existing in traditional passive hydraulic filter, a concept of hydraulic filter with active control is presented. Based on its simple operation principle, the theoretical analysis for a kind of active control hydraulic filter with static pressure balance and variable chamber, driven by double accumulator-piezoelectric crystal, is carried out, and its attenuating principle is understood. In order to describe the united operating characteristics of hydraulic system composed of pump, pipe line and load, the accurate mathematical models of pump and load, and the matching method between pump and load are put forward.Finally, the selection method of the control law for achieving the desirable vibration absorption behavior is proposed considering hydraulic supply characteristics and hydraulic load characteristics reasonably.
