The pre-and post-processing system of vehicle-bridge coupling can effectively reduce the efforts on data preparation and analysis of results,which shows a significant value for vehicle bridge coupling in research and engineering design.
A prestressed continuous box girder bridge is analysed by using finite element method. Through the analysis of test result, it is concluded that the test method is reliable and feasible, the actual force and deformation is less than design value. The results of finite element calculating are in agreement with the test results, which shows the feasible test scheme and the test data.
The before-treatment system and after-treatment system of thiscomputing program are powerful and convenient because of its perfectinterface. It can be operated in windows 98/2000/XP.
As a practice of above idea and theory, this paper rewrites a structure analysis of finite element program which based on the object-oriented programming technology. Using current popular Visual C++ developing tool and ODBC database connectivity technology, this paper develops a data management program FEDMS of CAE software pre-processing and post-processing data.
此外,作为上述理论和方法的实践,重写了一个采用面向对象技术和有限元方法的通用平面杆系结构分析程序FINITE,应用当前比较流行的Visual C++开发工具的ODBC数据库连接访问技术,研制了一个后台基于Microsoft ACCESS数据库的CAE软件数据前后处理系统FEDMS(Finite Element Data Management System),对结构分析计算中的前后处理数据进行了有效的管理。
In the paper,the stress of throttling pipe of feedwsterregulating valve was analyzed in detail by the finite elementmethod and its mechanical model has been set.The thermo e-lastic—plastic stress end deformation was also calculated.Thefatigue life analysis was performed by Harbin Boiler Works.In the mesh time,It was shown to be similar that the results offinite element method were compared with th them of analysismethod.
Comprehensive Processor based on Finite-element- coupled with Bound-element-method for Marine Structures (CPFBMS) is introduced- Making use of the expert knowledge database, it is possible to operate interactively with both the pre- and the post-processing system. Comparisons have been made among various similar softwares, CPFBMS provides fairly acculate resu1ts using shortest operational houres by means of Microsoft windows. The range of application is very wide. Di-rect structual analysis are suitable for...
PREFEM & POSTFEM Systems for transverse strength analysis based on the result of 3-D beam finite element model are investigated and provided in this thesis. For the PREFEM System, the distinctive subarea mesh generation method and effective linear load discretion technique are used, while for the POSTFEM System many figures or tables can be choosed to show the result. The systems were applied in the structure analysis of a 32000dwt oil tanker analysis.
