Four-quadrant operation characteristic of hydraulic transformer

By studying the four-quadrants operation characteristic of hydraulic transformer,a dynamics model was built.The flow characteristic of hydraulic accumulator,the pressure characteristics of hydraulic constant pressure rail system and the control angel of hydraulic transformer were simulated.Results show that the pressure variation of hydraulic constant pressure rail system is not more than 3 percent and keeps at a nominal level.The flow of hydraulic accumulator and the control angle of the hydraulic transformer change with the load variation.
