本文针对φ130mm链径超大型锚绞机，重点研究其纯水液压控制系统中的液压柱塞泵。通过理论设计方法设计符合要求的纯水轴向柱塞泵。研究其运动学特性、动力学特性以及配流特性，提出优化结构的依据。本文研究的主要内容包括：
1．对纯水轴向柱塞泵的设计进行研究，提出其关键零部件的设计方法。根据
φ130mm链径超大型锚绞机纯水液压系统的工作需求，借助MATLAB的程序方法计算出纯水轴向柱塞泵的主要结构参数。
2．运用三维建模软件PRO/E对纯水轴向柱塞泵以及其相应的流场分别进行几何建模。在对柱塞泵进行几何建模的过程中，考虑到主要研究柱塞泵的动力学特性，对柱塞泵的壳体及支撑进行简化省略处理；在对流场进行建模的过程中，考虑到油膜影响建模分析的复杂性，在不影响分析结果的前提下对其进行简化忽略处理。
3．利用ADAMS建立该纯水轴向柱塞泵的物理模型。建立其刚性体模型，分析其运动学特性。对轴向柱塞泵的关键零部件进行柔性化处理，运用ADAMS和ANSYS等联合解决多体系统刚柔耦合动力学分析和仿真，分析其动力学特性。通过运动学特性和关键零部件的动力学特性来验证设计的合理性。
4．分析纯水轴向柱塞泵的配流特性。运用计算流体动力学CFD的技术手段，分析纯水轴向柱塞泵的流场规律。通过得出的压力、湍流动能等流场规律，优化配流盘结构，改善柱塞泵配流特性，提高工作性能。
