用恒压伺服泵站来做正弦动态加载，泵的流量达不到平均流量。。

暮雨潇潇

能利用伺服阀前加蓄能器来达到目标振幅吗？还是说泵的流量必须要达到平均流量，求指导

需要一个累加器。 蓄能器尺寸应约为一次冲程中使用的油量的10倍。 越大越好。 蓄能器应预先充电至系统压力的约90％，因此只有足够的油，但主要是气体。 这样压力将保持相对恒定。

这将减少旋转斜盘需要移动的量。 这将减少泵的磨损。

泵需要能够提供75％的峰值流量。 当需求高于75％时，蓄能器将供油。 80％更谨慎。

An accumulator is required.  The accumulator size should be about 10 times the amount of oil used in one stroke.  Bigger is better.   The accumulator should be pre-charge to about 90% of the system pressure so there is just enough oil but mostly gas.  This way the pressure will remain relatively constant.

This will reduce the amount the swash plate needs to move too.  This will reduce the wear on the pump.

The pump needs to be able to supply 75% of the peak flow.  The accumulator will supply oil when the demand is above 75%.   80% is more cautious.
