大型铁路站房的快速建模技术研究
Research on the Rapid Modeling Techniques for Large Railway Stations
摘要
Abstract
In order to establish a rapid finite element model of large railway stations for comparative analysis, a modeling program is compiled based on the Matlab platform.Firstly, the key techniques and programming concepts are elaborated in terms of node positioning and numbering, element numbering, and defining cross sections.The source codes of some main functions are also given.Then, the modeling process of Kunming South Station is taken as an example to demonstrate the advantages of the program such as improving the modeling efficiency, fast error-correction function based on visual windows, and ensuring the matching between model and drawing.Finally, the established ANSYS model and MIDAS model are compared, which shows consistent computation results of the two models in dynamic characteristics, and proves the efficiency and accuracy of the program.关键词
