How does a hydraulic cylinder convert power into mechanical energy?

When a power output is required, the hydraulic cylinder converts hydraulic energy into mechanical energy via the “TF.” The power bond graph of the EHA can be modeled by connecting the bonds of the three modules , . A “single-line” EHA model is frequently employed for computational and solution simplicity, as indicated in Fig. 8 (b) .

What is the energy flow between electric motor and hydraulic cylinder?

The energy flow between the electric motor, the hydraulic pump, and the hydraulic cylinder is illustrated in Fig. 8 (a), expressed as a bonding diagram . The electrical energy stored in the motor is converted into mechanical energy by the gyrator, which is designated as “GY.”
