| 柱塞泵的流量脉动是噪声流体传播的原因。为设计良好的配流盘以减少流量脉动和斜盘上的倾覆力，笔者建立了柱塞泵工作过程的数学模型。以流量脉动为目标，压力脉动作为结果进行分析；采用Amesim液压仿真软件分析柱塞腔内的增压、减压速率与流量波动的关系；在此基础上分析减压槽和配流盘上分度角等结构设计参数的影响，通过遗传算法优化得到一组参数帕累托解集，以此设计配流盘。排油流量和吸油流量变化仿真结果表明：采用该优化方法设计的配流盘，能有效降低柱塞泵流量脉动。该研究为正向设计配流盘结构、降低流量脉动提供了一种有效方法。 |

| The flow ripple of piston pump is the cause of noise fluid transmission. In order to design a good port plate to reduce the flow ripple, a mathematical model of the working process of the piston pump was established. The analysis was carried out with flow ripple as the target and the pressure ripple as the result; AMESim software was used to analyze the relationship between the rate of pressurization and decompression in plunger cavity and the flow fluctuation. On this basis, the effects of the structural parameters of the port plate such as decompression groove and graduation angle of the port plate were analyzed. A set of Pareto solution was obtained through genetic algorithm optimization to design the port plate. The simulation results show that the flow ripple of piston pump can be effectively reduced by using the proposed optimization method.The research provides an effective method for forward design of the port plate structure and reducing flow ripple. |
