中文摘要：

随着船舶向大型化、高速化方向发展,主机的功率越来越大,多主机并联工作模式随之出现。目前有采用电力推进以及机械推进方式来设计的,但机械传动与电力传动设备的功率重量比远远小于液压传动,因此提出船舶综合液压推进,将液压传动应用于船舶推进系统。本文对其推进原理以及特点进行论述,同时为其开发一模拟试验台,为船舶动力系统重新设计提供了新的思路。

英文摘要：

Along with the development of ship tends towards high-speed, large-scale and high-power, power of the host engine becomes larger and larger. The model of several engines work together in parallel has been put forward. There are mechanical drive and electrical drive mode. However, the ratio of power to weight of these two driving modes is far smaller than hydraulic drive. So integrated hydraulic propulsion （IHP） was put forward. The principle and characteristics of IHP ship was discussed. The simulated test-bed of IHP method was introduced. This provides a new idea for the redesign of ship power system.
