Single crystal blade impact test measurement data correction method and correction system

Abstract

The invention provides a single crystal blade impact test measurement data correction method and correction system used for correcting a to-be-corrected file generated after a reference data file is cut off, and relates to the field of data analysis. The correction method comprises the following steps: reading a to-be-corrected file, and extracting attribute information of each channel of the to-be-corrected file; determining channel codes of the to-be-corrected file according to the channel attribute information of the to-be-corrected file and the one-to-one correspondence between the channelcodes and the channel attribute information, and arranging the channel codes of the to-be-corrected file according to a preset sequence to obtain channel information of the to-be-corrected file matched with the channel information of the reference data file; and modifying and outputting the modified file according to the channel information and the preset parameters of the to-be-modified file. According to the single crystal blade impact test measurement data correction method and correction system, the channel information lost due to data truncation can be found, and the reliability of dataanalysis is ensured.

Description

technical field [0001] The present disclosure relates to the field of data analysis, in particular to a method and system for correcting measured data of a single crystal blade impact test. Background technique [0002] With the development of the big data era, data analysis has become an important way to deal with big data. Generally, data analysis refers to the process of analyzing a large amount of collected data with appropriate analysis methods, extracting useful information and forming conclusions to study and summarize the data in detail. For example, single crystal blade impact test measurements can be studied in detail through data analysis. [0003] Due to the short duration of the effective shock response signal in the shock test, generally no more than 2 seconds, but due to the high sampling frequency and the long pre-acquisition time of the data acquisition system, the data file is relatively large, and there are many useless data, which brings a lot of trouble...

AI Technical Summary

Problems solved by technology

[0003] Due to the short duration of the effective shock response signal in the shock test, generally no more than 2 seconds, but due to the high sampling frequency and the long pre-acquisition time of the data acquisition system, the data file is relatively large, and there are many useless data, which brings a lot of trouble to the later data analysis. Therefore, it is necessary to truncate the file and extract the part containing valid response data for data analysis. However, some data acquisition software, such as Test.lab, after truncating the UNV format data file, the file information is incomplete, and the channel information part Lost, the channel code of the truncated data file cannot be determined, so it is impossible to judge the reliability of the data analysis
