矩形滑塊雙定子軸向液壓馬達的理論與實驗研究
[Abstract]:The general quantitative motor can not be realized when multi-stage torque and speed output are required in actual working conditions. According to the basic principle of motor, a series of new motors based on double stator structure are developed. In the "double stator" structure, one rotor and two stator cooperate with each other, without changing the input flow rate of the motor and without complex variable mechanism, this new type of motor passes through different feed. The connection of the outlet can output a variety of rotational speed and torque. If it is used as a pump, it can work at different pressure and output different flow rate to meet the need of the system without reducing the pressure valve at the same time. This saves pumps, motors and valves in the hydraulic system and saves energy consumption. In this paper, the axial hydraulic motor with rectangular slider and double stator is studied. In this paper, the research status and development trend of hydraulic technology and axial hydraulic motor are summarized firstly. After analyzing the deficiency of the existing hydraulic motor in practical application, a new type of principle motor with double stator structure is proposed. The single-acting multi-pump multi-motor drive in multi-pump multi-motor system is discussed in detail. On this basis, a comprehensive theoretical and simulation analysis of the motor is carried out, including the kinematics and mechanical characteristics of the motor. The mathematical model of displacement, velocity and acceleration of the slider and the mathematical model of the output instantaneous angular velocity and torque of the motor are established when one motor and two motors work at the same time. According to the size of the actual prototype of the motor, the Matlab simulation is carried out, and some unique characteristics of the motor are obtained. The leakage path of the new motor is discussed in depth, and the mathematical model of the main leakage surface of the motor is obtained, and the instantaneous angular velocity variation of the motor output when considering the leakage is simulated and analyzed. The movement and force of the main moving parts of the motor are simulated and analyzed, and the correctness of the mathematical model of the motor is verified. At the same time, some shortcomings in the design of the motor prototype are found. The static flow field analysis of motor vertical distribution pair is carried out by using Fluent software, and the distribution law of hydraulic oil velocity and pressure is obtained, which lays a foundation for studying the supporting characteristics and leakage pulsation of motor distribution pair. Finally, the correctness of the motor principle is verified by the prototype test, and the work of the whole paper is summarized and the future work is prospected. Through the above research work, a more comprehensive mathematical description and simulation results of the new motor are obtained, which provides a theoretical basis for the prototype of the motor to be finalized in a short time, to reduce the cost, and then to enter the stage of actual production. The analysis and simulation method used in this paper can also be used as a reference for the development of other hydraulic components.
