摘　　要：围绕大型气候实验室和飞机的系统类型多带来的数据量大、耦合程度高、关联性强等问题,研究基于评定要素的多源气候试验数据特征分析与数据库设计方法。本文通过分析气候实验室环境特征、飞机气候试验历史数据和运行机理,析出了能够表征极端环境下飞机环境适应性的典型评定参数,研究了气候实验室数据、飞机环境响应数据和数据网络架构,进而实现多维、多源、海量气候环境试验数据的解耦,随后依据气候环境试验数据特征分析了时序数据、非时序数据和小子样试验数据的预处理分析算法,剔除异常值得到高质量的气候试验数据。并且利用高效精简的气候试验数据构建了气候环境试验数据库架构,形成了基于元数据的全海量试验数据抽取-存储-检索一体化方法,可实现气候环境试验数据的快速访问和高效分析,支撑气候环境试验的高效实施。The paper inwestigates the characterization and database design of multi-source climate test data based on assessment elements,whtch is based on the large amount of data,high coupling and strong correlation calused by the oultiple system types of large climate laboratories and aircraft.In this paper,e analyze the environmental characteristics of climate laboratory,aircraft climate test history data and operation mechanism,analyze the typical evaluation parameters that can characterize the environmental adaptability of aircraft under extreme environment,study the cl imate laboratory data,aircraft environmental response data and data network archi tecture,and then realize the decoupling of multidimensional,multi-source and massive climate test data.The pre processing analysis algorithm of the data,non-time series data and sub-sample test data is then analyzed based on the characteristics of the climate test data。and the anomalies are eliminated to achieve high-quality climate test data.In addition,we constructed a database architecture for clinate test data with efficient and streamlined cl imate test data,and formed a metadata-based integrated method for extracting,storing and retrieving the whole massive test data。which can realize fast access and efficient analysis of climate test data and support efficient implementation of climate test.
