Get lrm decomposition conditions in the vibration test integrated electronic module mount method

Vibration Test conditions Decomposition acquiring LRM module integrated within an electronic mount method proposed by the invention, is intended to provide a test to avoid over or under test, the test results close to the real situation, the electronic module integrated mounting bracket (MIR) integral vibration test method for decomposing conditions. The present invention is realized by the following technical scheme: the first MIR shelf space is divided into several separate areas; in the selected area field replaceable modules (the LRM) on the installation position and the number of key points monitoring point, an acceleration sensor is mounted, in vibration table vibration exciter, an acceleration response spectrum acquisition critical points and monitoring points acquired by the dynamic signal analyzer; tolerance statistical processing method for testing integrated spectrum data; straight segments with their equivalent method to test spectrum normalization specification spectrum; Comparative test and verification specification test spectrum, the spectrum was consistent response contrast, comparing spectral peaks similar code spectra, as appropriate MIR vibration test conditions as the test results of vibration test conditions independently of LRM.
