Abstract:Loading control system is the key control mechanism in static strength test of structures. The loading data will directly reflect the loading condition of the test piece. At present, the data output format provided by MOOG loading control system is not intuitive enough to read,which increases the difficulty of data processing for the test personnel. For thie reason, a software desing method based on LabVIEW is proposed in this paper. The orignal load data of MOOG isprocessed twice and converted into a common data format to realize the automatic calculation of relative error of load control channel and automatically generate load control data report. The software design method greatly reduces the difficulty of data processing and shortens the period of data processing. Onthe basis of improving work efficiency, the error rate of manual operation is reduced, which is helpful for the data analysisi of aircraft structural strength test. Key words: structural strength test; MOOG loading control system, LabVIEW, data processing.
