| 摘 要： | 为了快速建立大型铁路站房的有限元模型,以实现多款软件的对比分析,基于Matlab平台编制建模程序。从节点定位与编号、单元编号、赋予截面等过程,详细阐述该程序的编制思想和关键技术,并给出主要功能的源代码。以昆明南站的建模过程为实例,详细演示该程序在提高建模效率、基于可视化窗口进行快速纠错、保证模型与图纸相匹配等方面所具有的优势。最后,将建立的ANSYS模型和MIDAS模型进行对比,二者计算得到的动力特性保持一致,证明该程序的高效性及准确性。

| 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. |
