| 摘 要： | 泵控单出杆液压缸节能高效，是未来液压系统发展的方向，但是单出杆液压缸两腔的有效面积不相等引起的流量不平衡一直限制着泵控单出杆液压缸的发展与应用。普通轴向柱塞泵进出油口流量相等与单出杆液压缸的大小腔流量不匹配。为了解决这个问题，将普通轴向柱塞泵改进为非对称轴向柱塞泵，在此基础上探究非对称轴向柱塞泵配流机理，完善非对称轴向柱塞泵设计理论，对非对称轴向柱塞泵配流窗口包角和单出杆液压缸面积比的关系进行理论分析并推导其数学模型。设计与不同面积比单出杆液压缸匹配的非对称轴向柱塞泵的配流盘，在计算机仿真软件AMESim中建立非对称轴向柱塞泵和非对称轴向柱塞泵控单出杆液压缸系统的物理模型，在不同工况下对非对称轴向柱塞泵的进出口流量以及对非对称轴向柱塞泵与不同面积比的单出杆液压缸匹配情况仿真分析。仿真结果表明，使用非对称轴向柱塞泵能够补偿单出杆液压缸两腔的有效面积不相等引起的流量不平衡，使非对称轴向柱塞泵与单出杆液压缸的流量完全匹配。 |

Distribution Mechanism of Asymmetric Axial Piston Pump
College of Mechanical and Vehicle Engineering, Taiyuan University of Technology, Taiyuan 030024, China
| Abstract: | Pump-controlled single-rod hydraulic cylinders are energy-saving and efficient, which is the development direction of hydraulic systems in the future. However, the flow imbalance caused by the unequal effective areas of the two chambers of single-rod hydraulic cylinders has always restricted the development and application of pump-controlled single-rod hydraulic cylinders. The flow rate of the inlet and outlet ports of the ordinary axial piston pump is equal and the flow rate of the large and small chambers of the single rod hydraulic cylinder does not match. In order to solve this problem, the ordinary axial piston pump is improved into an asymmetric axial piston pump, on this basis, the flow distribution mechanism of the asymmetric axial piston pump is explored, and the design theory of the asymmetric axial piston pump is improved. Theoretical analysis of the relationship between the angle of the distribution window of the asymmetrical axial piston pump and the area ratio of the single-rod hydraulic cylinder is carried out, and its mathematical model is derived. Design of valve plates for asymmetrical axial piston pumps to match single rod hydraulic cylinders with different area ratios. The physical model of the asymmetrical axial piston pump and the asymmetrical axial piston pump controlled single-rod hydraulic cylinder system was established in the computer simulation software AMESim. The simulation analysis of the inlet and outlet flow of the asymmetric axial piston pump under different working conditions and the matching of the asymmetric axial piston pump and the single-rod hydraulic cylinder with different area ratios. The simulation results show that the use of an asymmetrical axial piston pump can compensate the flow imbalance caused by the unequal effective areas of the two chambers of the single-rod hydraulic cylinder, so that the flow of the asymmetrical axial piston pump and the single-rod hydraulic cylinder can completely match. |
