中文摘要：

为了从理论上研究奇数和偶数柱塞油缸对轴向柱塞泵流量脉动的影响，给柱塞泵的设计与选型提供理论依据，在轴向柱塞泵理论流量特性的基础上，考虑了配流盘结构的因素，发现柱塞油缸数的奇偶性对轴向柱塞泵流量脉动影响并不大。偶数柱塞个数的轴向柱塞泵也实际可行。

英文摘要：

In order to study the influence of odd and even axial pistons on flow fluctuating of axial piston pump theoretically, by considering the factor of structural design of port plate, the flow characteristic of axial piston pump was discussed. The result shows that the parity of the number of pistons has little impact on the flow ripple. The even axial piston pump is also practical.
