摘　　要：对斜盘式轴向柱塞泵中球面配流盘上的三种典型阻尼槽过流面积进行数值解析,提出一种过流面积解析方法,并将计算结果与流场仿真所得的等效过流面积进行对比,再利用已获得的过流面积得出柱塞泵的流量脉动曲线。结果表明:该球面配流盘阻尼槽过流面积计算方法物理意义明确,计算精度高;不同的阻尼槽过流面积对柱塞泵出口的流量脉动率有很大影响。Three types of typical relief groove flow areas of the spherical valve plate in axial piston pump are analyzed numerically. An analytical method of flow area is put forward and the results are compared with the equivalent area got from CFD simulation. The flow ripple curve is obtained using the flow area. The research results show that this method of calculating damping groove flow area has specific physical significance and high computational accuracy. The damping groove flow area has a great influence on the flow ripple of piston pump.
