摘  要：
基于配流盘过渡区优化的传统轴向柱塞泵降噪方法是在过渡区配流结构已知的前提下进行反向参数优化,缺少普遍性的指导意义。首先对轴向柱塞泵流体噪声和结构噪声激振源形成机理进行分析;在此基础上以消除柱塞腔压力冲击和控制柱塞腔流量倒灌峰值及分布位置为设计目标,提出开式轴向柱塞泵孔槽结合配流方式正向设计理论;采用轴向柱塞泵流动特性仿真模型,对此设计理论设计的配流盘的降噪效果进行分析,仿真结果表明可以显著降低轴向柱塞泵出口流量脉动幅值,基本消除柱塞腔压力冲击。由于此设计方法是基于目标驱动的,可以指导不同型号国产轴向柱塞泵配流盘的设计。

Axial piston pump Noise reduction Flow ripple Valve plate Forward design
摘  要：
Traditional noise reduction method for axial piston pump by optimizing the transition area in the valve plate is based on specific structural parameters,which is of less meaning for valve plate design.The formation mechanism of the noise excitation sources of hydraulic noise and structural noise for axial piston pump was discussed.Then,aiming at elimination of the pressure overshoot in piston chamber,and control of the peak value and position of backflow into piston chamber,a forward design theory of distribution method with damping orifice and damping groove for axial piston pump was proposed.Finally,a valve plate was designed based on this design theory.The noise reduction effect of this valve plate was analyzed.Results showed that the application of this design method could reduce the flow ripple amplitude apparently and the pressure overshot could be almost eliminated.Because the structure of the damping groove was not appointed,this design theory can be used in the valve-plate design of different domestic axial piston pumps.
