摘　　要：为了解该新型轴向柱塞泵的基本性能,借助动力学仿真软件ADAMS及液压系统仿真软件AMESim,并引入有限元柔性体,搭建刚柔耦合、固液耦合的浮杯泵虚拟样机,对泵的运动学、动力学及液压性能进行仿真研究。通过仿真得到了该泵的运动学规律、主要部件的受力情况,以及泵的出口流量及压力波动情况。结果表明,由于柱塞数目的增多,使得该泵具有波动小、运行平稳的优势;同时,由于泄漏点的增加,该泵的泄漏量增加。The 3D floating cup pump model is built based on the virtual prototype technology （VPT）.With the aid of the dynamics simulation software ADAMS and the hydraulic system simulation software AMESim,introducing the finite flex body,we build a rigid-flexible and solid-liquid coupling virtual prototype.The kinematic,dynamic and hydraulic characteristics of the FC pump are researched.The simulation result shows that,with the increase of the number of pistons,the flow pulsation ＆ pressure pulsation of the pump is getting smaller; but the leakage is increasing,because of the increasing of leak gaps.
