摘要
针对汽车风洞试验气动力测量装置的特性以及测量数据采集过程、数据处理的通用方法和处理结果的要求,建立对应的数学模型,开发了具有通用性的汽车风洞测力试验气动力数据处理软件。软件采用Visual Basic 6.0开发,通过读取txt格式的模型数据文件,对数据进行提取、分析计算和显示。软件集成Excel报表功能,使用人员能够直观地观察分析汽车风洞模型的气动力和气动力系数。论述了该软件系统的结构、数据处理方法和结果显示技术。该软件已经应用在湖南大学HD-2风洞汽车模型的测力试验中。
In view of the characteristics of experiment equipment for automotive aerodynamic force and the requirement of data processing and its result, a certain mathematic model was built. Also, software of automotive wind tunnel data processing was developed, by virtue of Visual Basic 6.0. The data was extracted, analyzed and displayed by reading data files in format TXT. The software integrated Excel software successfully. Users could observe and analyze the aerodynamic force and coefficient of automotive wind tunnel model intuitively. The paper discussed software structure, data processing method and display technology of the soft-ware. Finally, the software has already been used in the HD-2 wind tunnel test of Hunan University.
