摘　　要：为提高高速高压微型轴向柱塞泵球面配流副的配流性能,以单向旋转微型轴向柱塞泵球面配流副为研究对象,对预升压区结构进行优化。建立高速高压微型球面配流副预升压过渡区瞬时压力和三角槽过流面积与三角槽深度角等参数的数学模型;采用粒子群优化算法对预升压区进行结构优化;最后将原始模型与优化模型导入Fluent中进行仿真分析。结构优化结果为:深度角β=16.1°,宽度角α=56.3°,开口角∅=12.7°,错配角φ0=1.2°。优化后的预升压过渡区的压力脉动率比原始结构降低了4.6%,提高了微型轴向柱塞泵球面配流副的配流性能。In order to improve the flow distribution performance of the spherical valve pair of the high-speed and high-pressure miniature axial piston pump,taking the spherical valve pair of the unidirectional rotating miniature axial piston pump as the research object,the structure of pre-boost zone was optimized.The mathematical models of the instantaneous pressure in the pre-boost transition zone,the flow area of the triangular groove and the depth angle of the triangular groove were established.Then particle swarm optimization algorithm was used to optimize the structure of the pre-boost zone.Finally,the original model and the optimized model were imported into Fluent for comparative analysis.The structure optimization results are as follows:depth angleβ=16.1°,width angleα=56.3°,opening angle∅=12.7°,error angleφ0=1.2°.After optimization,the pressure pulsation rate in the pre-boost overpressure zone is reduced by 4.6%compared with the original structure,the flow distribution performance of the spherical valve pair of the miniature axial piston pump is improved.
