航天器运输的力学数据采集、存储和分析方法

The acquisition, storage and analysis of mechanical data in spacecraft transportation

为了实时地监测及分析航天器运输过程中的力学环境,提出了使用移动数据记录仪实现数据的本地自动采集和存储方法,可对采集的海量数据自动批处理进行参数的时域及频域分析,分析后结果可直接反映与力学环境要求指标的符合性;另外,可将采集的GPS信号与力学数据匹配进行多维分析,以指导后续航天器同路线的运输。

In order to monitor and analyze the mechanical environment during spacecraft transportation, a data acquisition, processing and analysis method is proposed, where a kind of mobile data recorder is used for the automatic and local acquisition of the data and the data storage. The mass data analyses both in time domain and frequency domain can be made to estimate the analysis results according to the requirements, and the acquired GPS signal can be analyzed combined with the acquired mechanical data to guide subsequent spacecraft transportations.
