| Abstract: |
| The integrated hydraulic transformer has a compact structure and no throttling loss in the process of pressure regulation. It is widely used in the common pressure rail hydrostatic transmission system. The integrated hydraulic transformer is realized by designing more than three ports on the distribution plate, and the voltage transformation characteristics of the integrated hydraulic transformer with different port numbers are different. In this paper, the influence of port number on the pressure ratio of integrated hydraulic transformer was studied, and the pressure ratio characteristics of 3-ports, 4-ports, and 5-ports integrated hydraulic transformer were obtained, and an experimental platform was built for experimental verification, which shows that the simulation results are consistent with the experimental results and provides a theoretical basis for the design of integrated hydraulic transformer. |
