【摘要】：本论文以Visual FoxPro 9.0为平台,搭建了一个复合材料层合板力学性能模拟数据库。此数据库主要包含以下三大模块:一、复合材料层合板力学性能模拟数据库维护模块。二、复合材料单层板力学信息查询模块。三、复合材料层合板强度模拟APDL代码自动生成模块。在数据库的搭建过程中,首先建立了上述三大模块的界面,再建立各模块间的数据连接关系,构成了本数据库的总体框架。接着对各模块界面进行了详细的功能设计及界面设计,添加了各控件及新建了所需的新方法程序及属性,并进行了相应的代码编写,最终构成本数据库。数据库的各模块功能如下:一、复合材料层合板力学性能模拟数据库维护模块主要有以下功能:在该模块界面用户能够对收集在数据库中的单层板基本力学信息如横向弹性模量、纵向弹性模量、纵向泊松比、面内剪切弹性模量、横向拉伸强度、横向压缩强度、纵向拉伸强度、纵向压缩强度及面内剪切强度等进行系统管理,包括添加、更改、删除记录等。也可将模拟得到的复合材料层合板工程力学常数信息及模拟条件信息收录到数据库中,方便之后的查询及管理二、复合材料单层板信息查询模块主要有以下功能:该模块可实现对单层板基础力学信息的查询,在该模块界面用户可通过设置“输出字段”、“查询条件”及“排序字段”等条件快速找到满足条件的复合材料单层板。三、复合材料层合板模拟代码自动生成模块主要有以下功能:该模块中包含了一个用ANSYS有限元分析软件支持的批处理语言APDL程序语言编写的代码框架,用户只需在模块界面上选择所需的复合材料单层板材料及铺层参数,数据库便会自动将所选单层板的工程力学常数及铺层数、铺层角与模型尺寸等数据自动填充入APDL代码框架中,自动生成一个程序代码文件,利用ANSYS可直接运行该程序文件,得到复合材料层合板的最终强度。
[Abstract]:In this paper, a simulation database of mechanical properties of composite laminates is built on the platform of Visual FoxPro 9.0. This database mainly includes the following three modules: first, the database maintenance module of composite laminate mechanical properties simulation. Second, the mechanical information query module of composite monolayer plate. Third, the composite laminated plate strength simulation APDL code automatic generation module. In the process of setting up the database, the interface of the three modules mentioned above is first established, and then the data connection relationship between the modules is established, which constitutes the overall framework of the database. Then the detailed function design and interface design of each module interface are carried out, and the new method program and properties are added, and the corresponding code is compiled. Finally, the database is constructed. The functions of each module of the database are as follows: 1. The main functions of the database maintenance module are as follows: at the interface of the module, the basic mechanical information such as transverse modulus of elasticity, longitudinal Poisson's ratio, and the basic mechanical information of the single layer plate collected in the database can be obtained by the user. In-plane shear modulus, transverse tensile strength, transverse compression strength, longitudinal tensile strength, longitudinal compression strength and in-plane shear strength are systematically managed, including adding, modifying, deleting records, etc. It can also be included in the database of engineering mechanical constants and simulation conditions of composite laminates, which is convenient to query and manage. The main functions of the information query module of composite monolayer plate are as follows: the module can query the basic mechanical information of monolayer plate, and the user can set "output field" in the interface of the module. Conditions such as query conditions and sort fields can quickly find composite monolayers that meet the criteria. Thirdly, the automatic code generation module of composite laminates has the following functions: the module includes a code framework written by APDL, a batch language supported by ANSYS finite element analysis software. The database will automatically select the engineering mechanical constants and the number of layers of the selected monolayer plate by selecting the material and parameters of the composite monolayer board on the interface of the module. The data such as laying angle and model size are automatically filled into the APDL code frame and a program code file is generated automatically. The program file can be run directly by using ANSYS and the final strength of composite laminates can be obtained.
