A Study On The Data Management And Database System Of The Fuze Design And Simulation

This thesis is an introduction of the database system, which combines the fuze design and simulation, and it is an introduction of the technology for preconditioning the data in the process of the simulation. It also introduces the design of fuze system, the process of simulation and the application of the database for fuze design and simulation, with the example of the horologe of some fuze system.This thesis gives an introduction of the development of fuze system and its design technology. Further research and analysis are also made on the diversified information and the data type. It developed the database system of fuze design and simulation system based on Visual Foxpro 5.0. This database system is developed on the based of relation model, and has been developed with the Object Oriented (OO) method. Since OODB (Object Oriented Database) is not fully developed, (although it is the direction of the Database system.) the combination of the RDB( Relation Database) and OODB has been an unavoidable tendency. The work done in this research is just an OO extension of fuze database system based on the relation model, which makes the system better in openness, and easy to maintain. Furthermore, this thesis has studied the characteristics of ballistic trajectory data of fuze system, and has developed the program for preconditioning the data in the process of the simulation, which is based on the least square method programming with Visual C++5.0 and has enhanced the feasibility of this system. This study is done on account of the fact that the discrete data can not be accepted by the simulation software-Working Model, which must be turned into successive function. To test this program, this study has also solved and analyzed the horologe in some fuze system, and has drawn a satisfactory conclusion. The database and the program for preconditioning the data are combined completely, which is easy to be used by the users.Finally, this thesis has introduced a modeling and simulation case of horologe in the fuze system, by using the MDT (Mechanical Desktop) and Working Model. It has also tested the database for fuze design and simulation system, and proved the usefulness of the database.The application by the users shows that the result of the research has brought about a friendly interface and an easy usage, which is very convenient to the designers. This software has been tested again and again, which shows that this software is stable, and has satisfied the users, enhances the efficiency of simulation, it also fulfilled the expected aim and gained the high evaluation.
