Working condition matching characteristic analysis of IHP system in several working modes

Aimed to be used in engineering ships, war ships and other special ships, integrated hydraulic propulsion (IHP) system is proposed. This system has a unified power source, can easily switch between several working modes, and can recover the stopping energy produced by propeller etc. The matching parts of the system mainly contain engines, propellers, pumps and motors. This paper focuses on the working condition matching characteristic of the system. Only consider the following two working modes: single engine single propeller and double engines double propellers. The matching characteristic of the system in these two modes is studied through the working condition matching characteristic chart. The results show that IHP system has a good matching characteristic. The operating range is wide, so IHP system is suitable for special ships.
