介绍了一种基于VB 后台调用ANSYS和MATLAB进行设计计算的方法。通过借助VB设计的参数化输入界面， 调用APDL编写的模型分析程序和MATLAB编写的可靠性计算程序，实现了在用户界面上以可视化的形式显示计算结果功 能，并应用于铁路接触网设计的可靠性计算中，结果显示证明了计算软件的可行性和实用性。(Describes the background of a call based on ANSYS and MATLAB VB design calculation. VB by using the design parameters of input interface, called APDL model prepared by the procedures and the reliability of computer program written in MATLAB, implementation in the user interface to visualize the results in the form of display features, and design used in railway catenary the reliability of the calculation, the results proved the feasibility and practicality of computing software.)

伪随机信号发生器，可生成PN63,PN511序列 ,调试通过，可直接使用，也可以稍微修改用在其他伪随机序列生成(Pseudo-random signal generator, can generate PN63, PN511 sequence, through debugging, can be used directly, or you can use a little change in other pseudo-random sequence generation)
