Research and application of fault prediction and health management technology for ship low-speed engines
In order to improve the stability and reliability of ship low-speed engines and the safety of ship navigation,the fault prediction and health management system architecture of ship low-speed engines were built in this study.Using the software GT-POWER,the simulation model database of low-speed engines was built,and a fault diagnosis method was proposed based on the integration of performance simulation,oil analysis and vibration analysis.On this basis,the fault prediction and health management system of marine low-speed machine was successfully developed and the bench test was completed.The self-designed and developed system prototype and client had been successfully applied to a 62,000 tons multifunctional pulp ship,which had operated safely and stably for more than 6000 hours,completed relevant real ship verification,and realized the whole life cycle management of the ship's main engine.This system opens up a new direction for the safe operation and maintenance of intelligent ships,having positive promoting and guiding significance to the construction of intelligent ships.
