| Most hull plates are non-developable spatial surface and their forming process is verycomplicated, therefore, an automatic hull plates forming system taking full advantages ofcomputers has always been the focus of attention. This paper investigates the relationbetween the plate form (final form and initial form) and the strain (in-plate strain andout-of-plate strain) distribution, proposes the in-plate strain and out-of-plate strain analysissystem during plate forming, and completes the analysis, design and coding realized of thesystem, which provides technical support for automatic hull plates forming process.First of all, the development purposes and functional requirements are introduced.And the system development and technologies are discussed, including the ABAQUSsecondary development technology and the object-oriented technology with UML. Afterthat, this paper carry out theory research of system, and propose a set of algorithms,including in-plane strain algorithm, out-of-plane strain algorithm. These algorithmspromote the system’s realization.After that, system feasibility analysis is proposed in this paper. Thanks to the UMLobject-oriented method, system requirement analysis and detailed analysis are impeded.After system fundamental functional requirements are determined, this paper refines thisrequirements into several modules based on the use case diagram, then preliminarilydefines the necessary classes in order to deal with the modules.Besides, this paper use object-oriented method to design the system in detail. On thebasis of the analysis above, the necessary classes’ whole attributes and operates aredefined. Then the system user interface are designed, and the coding realization areimplemented on the Visual Studio Development Platform.The system application test is impleted based on two typical working conditions, andtheir application process and results are introduced in detail. The test results reflect thatthe system can meet the function requirements. |
