Abstract: The technological evolution in the development process of the axial piston pump/motor is introduced in detail and its development trend is analyzed. In view of the main problems of the axial piston pump/motor, the research status at home and abroad is described. The emerging new technologies and new methods of the axial piston pump/motor on the basis of the progress of computer technology and electronic measurement technology are introduced. Finally, according to the development of axial piston pump/motor in China, some requirements are proposed, and the prospects are visualized. It is pointed out that so long as we follow closely the international trend and constantly bring forth new technologies and methods, our axial piston pump/motor technology will catch up forthwith and continue to play an important role in our modernization construction.

Key words: Axial piston pump/motor, Development, Model pump, Virtual prototype
