摘　　要：针对在进行接触网有限元分析中,改变接触网结构及载荷等参数需要再次进行建模计算的问题,研究开发出一套以VB.NET为平台对ANSYS进行二次开发的接触网专用计算分析系统。该系统根据接触网的结构特点,实现接触网的结构参数化建模,把MATLAB编写的M函数,用.NET Assembly编译成动态链接库文件,进行接触网的载荷参数计算,从而实现了接触网的静态计算、模态分析、谐响应分析以及谱分析。以接触网整体挠度分析为例,对比文献分析结果,从而验证了该快速化分析系统的正确性。When the parameters in the catenary structure are changed,the finite model has to be rebuilt and the calculating also has to be re-conducted. The catenary structure parameter model based on ANSYS is re-developed,the system performances are realized in VB.NET platform. According to the structure characteristics of catenary,parameterized modeling of catenary is realized. By using.NET Assembly,the M function written in MATLAB is compiled into dynamic link library file to calculate load parameter of catenary. The system can realize the contact net static calculation,modal analysis,harmonic response analysis,spectrum analysis. The simulating results are in good accordance with the results in related document which proves the correctness and feasibility of the model.
