【摘要】：液压传动被广泛应用于国防、冶金、航空航天等部门。轴向柱塞泵是现代液压传动中，使用较多的液压元件之一。重型液压机，行走车辆，军用武器等工业产品中都广泛地使用了轴向柱塞泵。传统的斜盘式和斜轴式轴向柱塞泵结构研究已趋于成熟，但噪声、泄漏、磨损、提高工作效率等问题仍有待进一步的改善。21世纪初荷兰Innas公司提出了一种新型浮杯式结构，对其工作性能进行了理论研究，并在2005年对第一台物理样机进行了试验研究。结果显示浮杯式结构在改善流量脉动、提高工作效率、降低噪声等方面都较传统结构具有一定的优势。本文在对浮杯式轴向柱塞泵的结构和工作特性进行了理论分析的基础上，在ADAMS和AMESim中分别建立了浮杯式轴向柱塞泵的动力学模型和液压模型。同时利用动力学仿真软件ADAMS和液压系统仿真软件AMEsim之间的接口模块将两个模型集成在一起，，建立了浮杯式轴向柱塞泵的联合仿真平台。利用联合仿真平台对浮杯式轴向柱塞泵的杯体运动特性、力矩传递特性、球形密封结构以及错位式配流结构进行了仿真研究。通过理论分析，结合仿真实验结果，得到了浮杯式轴向柱塞泵工作过程中一些基本参数的变化规律，总结了浮杯式结构相对于传统结构的优点，验证了错位式配流结构和空心球形头密封结构的优越性，为国内浮杯式轴向柱塞泵的进一步研究打下了基础。
[Abstract]:Hydraulic transmission is widely used in national defense, metallurgy, aerospace and other departments. Axial piston pump is one of the hydraulic components used in modern hydraulic transmission. Heavy hydraulic press, walking vehicles, military weapons and other industrial products are widely used axial piston pump. The traditional research on the structure of oblique disc type and inclined axis axial piston pump has become mature, but the problems of noise, leakage, wear and working efficiency still need to be further improved. At the beginning of the 21st century, Innas Company of the Netherlands put forward a new type of floating cup structure. Its working performance was studied theoretically and the first physical prototype was tested in 2005. The results show that the floating cup structure has some advantages over the traditional structure in improving the flow pulsation, improving the working efficiency and reducing the noise. Based on the theoretical analysis of the structure and working characteristics of the floating cup axial piston pump, the dynamic and hydraulic models of the floating cup axial piston pump are established in ADAMS and AMESim, respectively. At the same time, the joint simulation platform of floating cup axial piston pump is established by using the interface module of dynamic simulation software ADAMS and hydraulic system simulation software AMEsim to integrate the two models together. In this paper, the characteristics of rotor motion, torque transfer, spherical seal and staggered flow distribution of floating cup axial piston pump are studied by using the joint simulation platform. Based on the theoretical analysis and simulation results, some basic parameters of the floating cup axial piston pump are obtained, and the advantages of the floating cup structure compared with the traditional structure are summarized. The advantages of staggered flow distribution structure and hollow spherical head seal structure are verified, which lays a foundation for the further study of floating cup axial piston pump in China.
