舰船结构强度校核对于舰体结构安全具有重要意义。目前舰船结构强度校核主要是依据舰船通用规范进行，在根据舰船通用规范进行舰船结构强度校核时，规范要求条目繁琐，计算量庞杂，目前国内军船研究设计部门还没有高效的舰船结构强度校核软件。因此为了提高舰船的结构强度评估的效率和系统性，本文依据舰船通用规范结构设计要求，利用Visual Basic6.0具有数据库连接和数据处理技术，以Visual Basic6.0和Access数据库为开发平台开发了舰船结构强度规范校核系统。本文主要做了以下几方面工作：
（1）分析研究舰船结构通用规范、高速水面舰艇结构设计计算规则、水面舰艇结构设计计算方法，确定了舰船结构强度规范校核系统框架、强度校核内容、强度计算方法、强度标准等；
（2）应用Visual Basic6.0数据库数据接口技术创建舰船通用规范基础数据库。系统数据库收录了舰船通用规范的数据、图表、要求、规定等数据，同时系统可对一维二维离散数据进行拉格朗日插值计算，提高了舰船结构强度规范校核效率；
（3）应用Visual Basic6.0数据库数据接口技术创建系统型材库，系统型材库共收录了255种型材信息，为工程计算和系统计算提供数据支持，系统型材库可对型材信息进行更新、修改，删除等操作；
（4）基于Visual Basic6.0和Access为开发平台，开发舰船结构强度规范计算模块，该模块能完成主舰船总纵弯曲设计载荷计算、主船体总纵强度计算校核、局部结构强度计算校核、极限弯矩校核船体总纵强度、结构稳定性校核，主船体刚度校核；
（5）应用ADO数据对象和VBA技术，将Tribon系统内舰船结构剖面信息导入系统数据库。系统可利用Tribon舰船剖面信息进行舰船结构强度规范校核，提高了舰船结构强度规范校核速度和效率；
（6）舰船结构强度规范校核系统可将excel格式的剖面信息导入系统数据库进行计算，同时输出excel格式计算结果。用户可选择数据库内置的Datareport数据报表输出结构强度计算书，并连接打印机直接打印文本，还可以html文件导出计算结果。
本文以某舰艇结构强度计算书为测试算例，计算结果表明系统能够很好地完成舰船结构强度校核工作，显著地提高了舰船结构强度校核效率和质量，具有较强的实用价值。

Abstract
Naval ship structure strength check for hull structure security has the vital significance. Currently ship structure strength check are mainly on the basis of general specification for naval ships, according to general specification, the specification requirements entries trival and calculation is confused.the current domestic naval ships study design department have not efficient ship structure strength check software. In order to improve the ship structure strength check efficiency and systematicness.Based on a ship general specification requirements, under Visual Basic6.0 and Access database development platform,developing ship structure strength specification checking system., This paper mainly do the work as the following aspects:
(1) Analyzing the naval ship structure general specification, high-speed surface warship structure design calculation rules and the surface ship structure design and calculation method,we confirmed naval ship structure strength specification checking system frame work, strength check content, strength calculation method, strength standard etc;
(2) Appling Access database, SQL language and data interface technology under Visual Basic6.0 plateform, we build naval ships general specification foundation database. Importing naval ship general specification’s data, diagrams, requirements to system foundation database, System can operate Lagrange interpolation program complete numerical interpolation calculation, improving the system calculation efficiency.
(3) We establish a profile system database, including the 255 profiles which are important data for the engineering calculation and system calculation.We can update,edit and delete the profiles message under the profile database.
(4) Under the Visual Basic6.0 and Access database development platform, we development the naval ship structure strength specification calculation module, this module can complete the naval ship longitudinal bending design load calculation, the main hull longitudinal strength calculation and check , local structural strength calculation and check, ultimate bending moment longitudinal strength calculation and check, the structure stability calculation, the main hull stiffness calculation and check.
(5) Application of ADO data objects and VBA technology, we can import Tribon system section information into system database, and system can complete the longitudinal strength calculation, improving the ship structure strength calculation efficiency.
(6) System database can import excel format section information into sysytem foundation database and output the excel format calculation results of the naval ship structer specification check system. Users can choose datareport data report to output structure strength calculation, print datareport data report, and generate HTML documents.
Taking one naval ship structure strength calculations for example, the system can perform well in ship structure strength calculation and check, improving the ship structure strength check efficiency and quality.the naval ship structure specification ch..
