Abstract: The static stiffness of the hydraulic transformer controlled system is researched. Based on the working principle of the hydraulic transformer controlled system, the system model is built. According to this system model the static stiffness models of the hydraulic transformer controlled motor and cylinder are established respectively, and the impact factors of the stiffness are analyzed. The static stiffness models of the pump controlled motor and cylinder are also deduced. Contrast experiments and simulations are carried out. Results indicate that compared to the pump controlled system, the stiffness of the hydraulic transformer controlled system is a little smaller. The static stiffness changes with the variation of the displacement of the hydraulic transformer oil port. According to the analysis, properly increasing the control angle of the hydraulic transformer is helpful to increase the pressure adjusting range of the hydraulic transformer controlled system and improve the static stiffness.

Key words: fluid power transmission and control, hydraulic transformer controlled system, static stiffness, pump controlled system, hydraulic transformer controlled angle
