在轴向柱塞泵的设计中，配流盘的设计是一个非常重要的问题。设计良好的配流板既可以减小流量脉动，又可以减小斜盘上的振荡力。在本研究中，利用计算工具CASPAR研究了配流板设计对流动脉动（流体噪声）、振荡力（结构噪声）和容积效率的影响。各种阀板设计参数的影响，如预压缩槽，交叉端口，分度和额外的预压缩体积将通过CASPAR的模拟结果来展示。该研究还详细说明了位移腔内的增压和减压速率与流动脉动、施加在斜盘上的力以及冲动斜盘所需的控制努力之间的直接关系。降噪技术对容积效率的影响也将通过模拟结果进行介绍。ASME版权所有©2006
In designing an axial piston pump, lot of attention is given to the design of the valve plate. A well designed valve plate can reduce both flow pulsations as well as oscillating forces on the swash plate. In the presented study, a computational tool, CASPAR, has been used for investigating the effect of valve plate design on flow ripple (fluid borne noise), oscillating forces (structure borne noise) and volumetric efficiency. The impact of various valve plate design parameters such as precompression grooves, cross port, indexing and additional precompression volume will be presented using simulation results from CASPAR. The study also details how rate of pressurization and decompression inside the displacement chamber directly relate to the flow ripple, forces applied on swash plate and the control effort needed to stroke the swash plate. The effect of noise reduction techniques on volumetric efficiency will also be presented with simulated results.Copyright © 2006 by ASME
