Abstract Ship propulsion system performance is being put forward new requirements by the development of world shipping and shipbuilding technology。 As an important part of a ship main power plant of Marine diesel engine, the specific power, dynamic property, economical efficiency, and reliability of Marine diesel engine are being affected directly by the technology level of supercharger。 The problems of large amounts of data organization and storage in the process of the computer information-making effectively were being solved by database technology researches, reducing data storage redundancy in the database system, realizing data sharing, data security and efficiently retrieving data and processing the data。
Two diesel engine turbochargers are taken as the research objects。Firstly, the principle of the supercharger is learned; the role of the supercharger is understood; and the structure of the supercharger has to be analyzed。 Then, the data of different Marine diesel engine turbocharger products is collected to learn the different supercharger parameters, performance and effect。 Next, SQL Server database and Visual Basic programming are used to develop the Marine diesel engine turbocharger database with visual interface。 Therefore, the data of Marine diesel engine turbocharger products and the various parameters can be input to the database to achieve the purpose of convenient search。 In this way, the operation instruction of Marine diesel engine turbocharger database software can be compiled。
This topic designs and develops a database of Marine diesel engine turbocharger。 The database has a visual interface, which can save, modify, delete and rebuild data and can query engine and exhaust gas turbocharger matching results。 And it has query function at the same time, the Marine diesel engine turbocharger products collect data and the various parameters to the database, achieving the purpose of convenient search。
