Abstract In order to improve the NVH (noise,vibration and harshness) performance and sound quality of fuel pumps,the pressure fluctuation control of the regenerative pumps for the fuel sys -tem is carried out.The pressure fluctuation characteristics of a regenerative pump were studied by the CFD numerical simulation and theoretical analyses.Two impellers with different degree of uneven blades were designed by the method of random blade distribution.An improved design method of the uneven blade distribution impeller was developed based on the CFD numerical sim -ulation and theoretical analyses.The noise test for the fuel pump of the pressure fluctuation con-trol scheme was conducted to verify the feasibility of the scheme.Results showed that the high-pitched noise disappeared in the high frequency and the NVH performance was improved for the fuel pump with uneven blade distribution impeller compared with even blade distribution impeller.Random uneven blade distribution impeller could significantly disperse the peak value of the blade passing frequency.With the degree of the uneven distribution blades increasing,the amplitudes of blade passing frequencies decreased more.Therefore,the use of random uneven blade distribution method helps to improve pressure fluctuation characteristics of the regenerative pump and to provide an important engineering value for the fuel pump NVH performance improvement.

燃油系统旋涡泵压力脉动的控制研究
为了改善燃油泵噪声、振动、声振粗糙度（noise，vibration and harshness，NVH）性能，提高燃油泵声音品质，开展了燃油系统旋涡泵压力脉动的控制研究。采用计算流体动力学（Computational Fluid Dynamics，CFD）数值模拟方法和理论分析方法分析燃油系统微型旋涡泵的压力脉动特性，并采用随机叶片分布方法设计了2种非均布程度不同的非等距叶轮。基于CFD数值模拟结果和理论分析结果，提出一种改进的非等距叶轮设计方法。燃油泵噪声试验结果验证了该设计与控制方案的可行性。结果显示：相较于等距叶轮，随机非等距叶轮燃油泵的中高频段尖锐噪声消失，NVH性能提升；随机非等距叶轮能够显著分散叶频峰值，非均布程度的增加显著增大了随机非等距叶轮的叶频脉动幅值下降幅度。因此，采用随机叶片分布方法，有助于改善旋涡泵的压力脉动特性，对改善燃油泵的NVH性能具有重要的工程应用价值。
