摘要
动力系统可谓舰船的心脏,直接决定了舰船的航行速度、输出功率和可操作性等重要指标。船舶工业经过近百年的发展,船舶发动机技术也不断改进,从最初的蒸汽发动机逐渐发展为新一代的涡轮式发动机。本文的主要介绍对象就是船舶涡轮式发动机,该类型发动机的最大优点是在原有发动机排量的基础上,有效提高发动机的功率,因此广泛应用于飞机、轮船等大型机械设备。本文首先对船舶涡轮式发动机的原理与组成进行简单介绍,建立涡轮发动机的函数模型,并在此基础上研究了船舶涡轮式发动机瞬时转速的预测方法,在船舶涡轮式发动机故障诊断等方面有重要意义。
the power system can be described as the heart of a ship,which directly determines the navigation speed,output power and maneuverability of ships.After nearly a hundred years of development history,ship engine technology has been constantly improved,from the initial steam engine to a new generation of turbine engines.The main object of this paper is the ship turbine engine.The greatest advantage of this type of engine is to improve the engine power effectively on the basis of the original engine displacement,so it is widely used in large machinery and equipment such as aircraft,ship and so on.In this paper,the principle and composition of the marine turbine engine are briefly introduced,and the function model of the turbine engine is set up.On this basis,the prediction method of the instantaneous speed of the marine turbine engine is studied,which is of great significance in the fault diagnosis of the marine turbine engine.
