摘要

作者讨论了泵排量对电静液致动器性能特性的影响，以及在电静液致动器中使用变量泵可能带来的优势。讨论的问题是加热，尺寸和刚度。值得注意的是，EHA提供了通过改变泵排量来改变耦合比的可能性。可变耦合比可以提高致动器的刚度，减小封装尺寸，减少封装发热。采用可变排量泵的EHA已被设计和制造，一旦组装完成，将对执行器进行测试。

Variable displacement electro-hydrostatic actuator

The author discusses the effects of pump displacement on electro-hydrostatic actuator (EHA) performance characteristics and the possible advantages of using a variable displacement pump in an EHA. Issues discussed are heating, size, and stiffness. It is noted that the EHA offers the possibility of varying the coupling ratio by varying the pump displacement. The variable coupling ratio could be used to increase actuator stiffness, to decrease package size, and to decrease package heating. An EHA employing a variable displacement pump has been designed and built, and the actuator will be tested once assembly of the package is completed.<>
