摘要: 为建立规范高效的风洞试验数据系统，提高数据处理与分析的可靠性和自动化、智能化水平，制定完善了试验数据处理方法、流程、符号接口等规范，采用面向服务的软件架构及异构数据存储管理、基于动态编译的自定义公式扩展、基于元数据与模板的文件可视化排版等技术，解决了处理方法与流程控制、数据流转与输出等通用化的关键问题，建立了多风洞共享、多试验类型通用的试验数据处理与分析系统。应用3年来，完成高速所6座风洞占试验总车次71.2%的数据处理，覆盖单/多天平测力、测压、通气测力、混合测力测压、喷流及部分特种试验等类型，系统具有规范、高效、开放的特点，是一种具有推广应用价值的风洞试验数据系统解决方案。Abstract: In order to improve the standardization and efficiency of the wind tunnel test data system and improve the reliability and automation of data processing and analysis, a general test data processing system is established for multiple wind tunnels and a variety of test types. On the basis of standardized data processing methodology, processes, symbols and formats, the general system uses the service-oriented software architecture, heterogeneous data storage management, the user defined formula expansion based on dynamic compilation, and the visualized file format editing based on metadata and template. Key problems of the general system are solved, such as the system architecture, processing methods and process control, data flow and file output, etc. In the last three years, 71.2% of test data of 6 wind tunnels in the High Speed Institute of China Aerodynamics Research and Development Center were processed by the general system, covered test types including single and multiple balances forces and moments measurement, pressure measurement, venting measurement, mixed forces and pressure measurement, jet test and some special tests. With the characteristics of being universal, efficient, and open, the general system is a data processing and management solution that worth promoting.
