摘　　要：In order to supply theoretical guidance to hydraulic transformer's design and application,the effect of the number of plungers in hydraulic transformer on its flow characteristic is analyzed,theoretical analysis and simulation are done on hydraulic transformer's flow characteristic when the number of plungers is different.Based on the working principle of swash plate piston hydraulic components,mathematical models of instantaneous flow and flow pulsation rate are built,and simulation study is done with MATLAB.As a result,the effect is found,and some conclusions worth referring to are obtained.In order to supply theoretical guidance to hydraulic transformer＇ s design and application, the effect of the number of plungers in hydraulic transformer on its flow characteristic is analyzed, theoretical analysis and simulation are done on hydraulic transformer＇ s flow characteristic when the number of plungers is different. Based on the working principle of swash plate piston hydraulic components, mathematical models of instantaneous flow and flow pulsation rate are built, and simulation study is done with MATLAB. As a result, the effect is found, and some conclusions worth referring to are obtained.
