摘　　要：泵和马达是液压系统中最重要的设备之,设计实验过程非常复杂,周期长、成本高。本文介绍了仿真技术的基本原理和一系列具体的仿真方法,重点分析了有限元、计算流体力学、多体仿真、流体仿真等仿真技术;较为详尽地阐述了这些方法在液压泵、液压马达开发中的应用;利用相应的仿真技术能够确定其关键部位的三维结构、受力状态、流场分布以及性能特点,从而大大提高开发效率和可靠性,实现设计优化,提高产品的性能和质量。Motor and pump are the most important parts in the hydraulic system. This paper introduced the basic mechanism of simulation technology firstly. Then, a series of specific simulation methods are put forward, which include finite element analysis, computational fluid dynamics, multi body simulation, hydraulic simulation. Essential spot can be determined through the analysis the structure, and take good use of physical property. The process of vigorously application simulation technology will greatly enhance the speed of development in the pump and motor development. Simulation has thus become an important factor in reducing development time, heightening product performance and product quality.
