【摘要】 本论文介绍了为引信设计、仿真集成系统所开发的数据库系统及仿真数据前处理技术，并以引信系统钟表机构为实例，介绍了引信系统设计、仿真过程及引信系统数据库的应用。在论文中，介绍了引信及其设计技术的发展。对引信设计、仿真集成系统的各种信息和数据的类型进行了深入研究和分析，应用Visual FoxPro5． 0数据库管理系统开发了引信设计仿真系统数据库。该数据库系统的开发工作是基于关系模型，并用面向对象的方法进行了扩展。面向对象数据库系统(OODB)是数据库管理系统的一个发展方向，但是还非常不成熟，把关系型数据库(RDB)和面向对象数据库系统(OODB)进行集成己成为一种势在必行的趋势，本论文工作就是对基于关系模型的引信系统数据库进行了的面向对象的扩展，使系统开放性好，易于维护。另外，在利用Working Model对引信系统进行运动学和动力学仿真时，需要输入现场试验测得的数据，而这些离散的试验数据，必须进行计算和前处理(函数化)，才可以应用于仿真，本文就此问题深入研究了引信系统的弹道数据的特点，并基于VisualC++5． 0，利用最小二乘法开发了仿真数据前处理程序，使仿真过程可以顺利、方便地完成。并且针对本拟和程序，对引信系统保险机构进行了解算，分析了解算结果，得到了满意的结论。引信系统数据库和引信仿真的前处理是紧密集成在一起的，方便了用户的使用。最后，本文介绍了利用三维造型软件MDT和动力学、运动学仿真软件Working Model，对引信系统的钟表机构进行了建模、仿真的应用实例。并结合此实例，对引信设计仿真系统数据库进行了测试，验证引信系统数据库在引信系统建模、仿真过程中的应用。用户应用结果表明，本论文的研究成果界面友好，易于使用，给设计人员带来了很大的方便。本系统经用户反复测试，运行稳定，满足了用户的需求，提高了引信设计仿真的效率，达到了预期目标，得到用户的好评。更多还原

【Abstract】 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.更多还原
