[Abstract]:The object of this thesis is variable control method and characteristic of axial piston pump. Based on the research of some common variable control methods, digital variable control of axial piston pump based on PWM high speed switch valve is proposed. The simulation models of mechanical hydraulic pressure control pump, mechanical liquid pressure flow compound control pump, mechanical hydraulic pressure flow power compound control pump and large displacement closed axial piston pump are built and analyzed. On the basis of this, the paper further builds the joint simulation model of digital axial piston pump (this paper is referred to as digital pump), and combines simulation with experiment to realize and verify the pressure control of digital pump. There are three control functions: pressure flow combined control and pressure flow power compound control. For the first time, LabVIEW and AMESim are used to establish the joint simulation model of digital pump, and on the basis of this model, the pressure of digital pump is controlled. The static performance of three control forms, pressure flow control and pressure flow power composite control, is simulated and analyzed. At the same time, the dynamic performance of pressure control, flow control and power control are simulated and analyzed. Finally, through the static performance test of digital pump, the functions of pressure control, pressure flow compound control and pressure flow power compound control are verified. The main contents of this paper are as follows: in Chapter 1, the variable control of axial piston pump is introduced. The research results of variable control at home and abroad are investigated, the research ideas and contents of this subject are determined, and the research difficulties are pointed out. In the second chapter, the working principle and static and dynamic performance of several common variable control pumps are introduced in detail. Finally, the static or dynamic performance of these variables is simulated and analyzed. In the third chapter, the relationship between the three control forms of digital pump and the hydraulic pressure control pump, the pressure flow compound control pump and the pressure flow power compound control pump is introduced. On this basis, the digital pump is divided into several parts to model. There are three models of high-speed on-off valve and three control modules. Finally, the establishment of digital pump joint simulation model is introduced. In chapter 4, the static and dynamic performance of digital pump pressure control, pressure flow compound control and pressure flow power compound control are simulated and analyzed. In chapter 5, the principle of digital pump test system is introduced, and the static performance of digital pump pressure control, pressure flow compound control and pressure flow power compound control are tested and verified. The sixth chapter summarizes the main research contents and points out the next research direction.
