| 摘 要： | 基于Windows平台，开发了大跨曲面屋盖风洞试验数据处理的可视化通用分析软件。介绍了针对脉动风压测试过程中的信号畸变处理方法、风压试验数据的表示形式、积分计算整体和局部气动力系数、软件的界面设计、基本的使用功能以及针对具体结构类型所采用的一些提高试验效率简化试验过程的措施，还采用神经网络方法对已测的风压系数数据进行精细化处理以准确地求取整个屋盖结构风荷载的完整特性。所开发的软件已经受多个大跨屋盖建筑物风洞试验的检验，在该类结构物风洞试验中发挥着非常重要的作用。

| Abstract: | A Windows based data processing program has been developed to analyze the huge number of sampled data in wind tunnel experiment for large span roof wind load test.The approach that is used to eliminate the signal distortion during the fluctuating wind pressure measurement,the method that is used to describe the tested result,the arithmetic that is employed to calculate the overall wind load force coefficient,the user interface design manner,the basic function of the developed software,and the skill that is used to simplify the experimentation for some special structures are described in this paper.Fuzzy neural network method is also employed to predicate the wind load property of the full roof structure.The developed software has been verified in wind tunnel test of several large roof structures and has been playing a very important role in the wind tunnel test for such structures. |
