摘　　要：针对轴向柱塞泵结构复杂、制造工艺和使用维护水平要求高、对油液污染敏感等问题,在介绍轴向柱塞泵工作原理与结构特点的基础上,详细分析柱塞的位移、速度、加速度,柱塞和缸体孔之间的受力。基于AMESim平台,建立柱塞运动单元模型,通过参数设置,进行仿真得到柱塞的位移和在缸体孔内的行程变化图线。发现柱塞的位移、速度、加速度正比于斜盘倾角的正切值、正弦值、余弦值,为轴向柱塞泵的进一步设计研究提供了依据。Because many shortcomings exist in the axial plunger pump,such as the complex structure,high requirements of manufacturing technology,use and maintenance,easy oil contamination and so on,this paper introduces its,the working principle and structure characteristics,analyses the displacement,velocity and acceleration of the plunger and the force between plunger and cylinder bore and based on the AMESim simulation platform,establishes the plunger motion unit model.By setting its parameters,the model is simulated,which is used to obtain the curve of the plunger displacement and travel change.It is found that the displacement,velocity and acceleration of the plunger are proportional to the tangent,sine and cosine values of the inclination angle of the swashplate.The basis is provided for further experimental design of the axial plunger pump.
