The failure of energy recovery with descending of regular hydraulic excavator's boom causes heat release problem, disfunction, and accelerated wear. According to this issue, this paper proposes a hydraulic excavator boom potential recovery system based on accumulator-hydraulic motor-generator. The accumulator of the system stores potential energy from construction of boom hydraulic cylinder through...
A semi-active control heave compensation system is proposed, according to the requirements of 6000m deep sea poly-metallic mining system. The heave compensation system is acted upon by interacting of dynamic vibration absorber with accumulator. Magneto-rheological damper is act upon actuator to take semi-active control of heave compensation system. The composition and principle of the heave compensation...
