基于Windows平台 ,开发了大跨曲面屋盖结构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
Based on the Windows platform, a visualization general analysis software was developed for wind tunnel test data processing of large-span curved roof structure.The signal distortion processing method, the representation of wind pressure test data, the integral calculation and Local aerodynamic coefficient, interface design of the software, basic function of use and some measures adopted to improve the test efficiency and simplify the test process for the specific type of structure. The measured wind pressure coefficient data is further refined by using the neural network method Accurately obtain the complete characteristics of the wind load of the whole roof structure.The software has been tested by wind tunnel test of several large span roof buildings and plays a very important role in the wind tunnel test of such structures
