摘要
在舰船推进系统中,系统仿真技术的应用非常广泛,如动力机械的性能分析、系统的动态特性预测、控制策略的研究及参数确定、设备系统的状态监测研究以及各类训练模拟系统的研制等。仿真工具选择与系统模型是仿真应用中的两个重要方面,各种不同的仿真工具各有特点,但它仅仅为系统仿真提供一个平台,而建模方法是确定仿真应用所具有的能力和可能存在的局限的主要因素。目前,在舰船推进系统性能仿真中采用的建模方法有多种,本文按照逐层分解的方法建立了推进系统的模块化建模体系,并给出了具体应用实例。
Marine propulsion system simulations can be used for a variety of purposes such as machinery performance analyses, maneuvering analyses, machinery control law studies and its parameters determination, equipment health monitoring studies and the development of simulators for education and training. In system simulation application, the selection of tools used for simulation and modeling method are two main points should be considered. Each tool has specific advantages and disadvantages but it alone provides only the platform, it is the modeling method which greatly determines the capabilities and limitations of the simulation. There are many modeling methods had been used in marine propulsion system simulation. In this paper, a modular modeling method is proposed which simplifies the system modeling by providing a breakdown to smaller subsystems and, finally, a real application example is given.
