摘要
对舰船喷水推进系统而言,动态工况下喷水推进泵的工作安全性是一个十分重要的研究课题,而控制系统参数设定的正确与否将在很大程度上决定动态工况下喷水推进泵能否安全可靠工作。首先建立了适用于系统动态工况仿真的舰船喷水推进系统数学模型及仿真模型,然后从避免喷水推进泵在动态工况过程中工作曲线进入使用限制区域的角度出发,重点对舰船加速和回转两类动态工况进行了仿真研究,并依据仿真结果对相应控制参数的正确设定提供指导。
The working safety of waterjet pump under transient process plays a very important part in the whole study on marine waterjet propulsion system, however, the working safety of waterjet pump is mainly decided by the factor that whether the development of the system control parameters is correct or not. The mathematical and simulative models of marine waterjet propulsion system suitable for system simulation under transient process were presented firstly; and then, from the aspect of preventing the operating curves of the waterjet pump from passing through the limited operating area under transient process, two kinds of transient processes including accelerating course and turning course were taken as main studying objects to be simulated, and the results derived form simulation are used to give a correct instruction of the development of the corresponding control parameters.
