摘　　要：结合非圆齿轮驱动式叶片差速泵的应用背景及其驱动原理,以叶轮叶片数为约束条件,提出非圆齿轮驱动式叶片差速泵驱动系统的多种设计方案。分析叶轮叶片数对叶片差速泵的排量、效率、振动噪声、流量脉动、叶片强度、工艺性等多个性能评价指标的影响。综合各评价指标,定义正、负理想方案,计算所提出的设计方案对正理想方案的贴近度。采用最优线性分派法对各驱动方案进行综合评价与选定,为后续叶片差速泵驱动系统的进一步设计提供依据。Combined with the application background and driving principle of the differential velocity vane pump driven by non-circular gear system,and the number of impeller vanes as the constraint condition,a variety of design schemes on its driving system of the differential velocity vane pump driven by non-circular gear are proposed.The influence of the number of impeller vanes on the performance evaluation index which include displacement,efficiency,vibration noise,flow pulsation,blade strength,process,and so on,is analyzed.The positive ideal scheme and the negative one are defined according to the comprehensive evaluating index,and then its approach degree of the design schemes to positive one is calculated;the different driving system is comprehensively evaluated and adopted by the optimal linear assignment method,which provides the basis for further design of the differential velocity vane pump-driven system.
