Abstract The vibration reduction and noise reduction has become a very important part in ship design and manufacture,which affects the comfort and safety of the ship。The vibration of ship is one of the key research of vibration reduction。In order to reduce the vibration caused by impact, we usually used a variety of vibration isolation methods such as single layer isolation,double layer vibration isolation and floating raft isolation etc。To reduce the vibration of the ship auxiliary system,thereby reducing the noise of ship。With the deepening of research,the types of vibration reduction system are becoming more and more persified。In order to study the performance of vibration reduction system,the influence of various parameters on the performance of the system is analyzed in this paper。
In the first chapter,the research of ship vibration reduction is reviewed at home and abroad,and the development process of the ship vibration damping system is introduced briefly。Secondly,the second chapter describes the basic functions of the MATLAB software and graphical interface GUI design methods and the preparation and use of the callback function。In the third chapter,the basic theory of the vibration reduction system is analyzed。In the fourth chapter, the dynamic model of the vibration reduction system of marine air compressor is established,and the numerical simulation based on Simulink is carried out,combined with GUI, the software of vibration reduction system was developed。 The fifth chapter,the 0。17/8 - V air compressor as object of analysis,which is produced by the Jaguar Compressor Manufacturing Co。 Ltd。 in Shanghai,the design of vibration reduction system, the selection of vibration isolation device, the calculation of vibration isolation efficiency and the effect of some parameters on the performance of the system have been developed by using the developed software。
