中文摘要：

为解决船舶在向大型化、高速化方向发展时船舶主机设计困难，机舱布置不合理以及机动性能差等问题，提出了一种新型船舶推进方式，即船舶综合液压推进。给出了该推进方式的推进原理，通过工况配合特性曲线图，对其工况配合特性进行分析，对该推进方式的优缺点进行讨论并对其重要组件液压泵以及马达进行设计计算。结果表明船舶综合液压推进具有其独特的优点，是对现有船舶推进方式的有益补充。

英文摘要：

Conventional ship propulsion methods meet some limitations in ship development towards high-speed, large-scale and high-power. A new ship propulsion method, integrated hydraulic propulsion （IHP）, was put forward to solve the problem. Then further research work was done on the principle of IHP method. Working condition-matching characteristic was discussed through the working condition matching characteristic chart. After that, the advantages and disadvantages of IHP method were given. And the pump and motor, important parts of IHP, was designed though physical analytical method. IHP method can be used extensively in some special kinds of ship for its own characteristics. To a certain extent, the limitation problem of ship propulsion method can be solved. IHP method diversifies the existing ship propulsion methods.
