Calculation of Hydraulic System of Movable Rigid Barrier Crawler Track

The load, speed and working requirements of a hydraulic system are analyzed and the load of its walking mechanism is calculated according to the composition of the hydraulic system of a movable rigid barrier crawler track, so the related parameters of the main components of the hydraulic system can be obtained. The type of the hydraulic components and driving components is selected according to the calculation results to satisfy the working requirements of the hydraulic system. Finally the type selection results are validated by verifying motion of the key function components of the hydraulic system, so it lays the foundation for system engineering implementation.
