    Abstract
  • With the developing of integrated technology of mechanical, electrical, hydraulic and control and the developing of digital hydraulic technology, a new integrated digital hydraulic actuation system (IDA) was put forward based on digital cylinder and edropump(electric-hydraulic-pump). The system composition and operating principle were analyzed. The mathematical models of the edropump, digital cylinder and the whole system were built in AMESim. Then, from the aspects of displacement response, overflow, motor speed and control valve opening and so on, it was simulated and compared with servo valve controlled hydraulic actuator (SHA) which was supplied by the centralized hydraulic oil source. Finally, the advantages and drawbacks of the integrated digital hydraulic actuation system were put forward.
