Discussion on Implementation Method of Vibration Test with Flexible Suspension Mode
The purpose of this paper is to discuss the new concept of flexible suspension for the combined aircraft external suspension in GJB 150.16A-200,which abandons the traditional methods of the finished product being rigorously connected to the vibration table.However,GJB 150.16A-2009 test standard for the implementation of the test only gives a systematic framework and principled control,for the specific implementation of the process of detail description and explanation is relatively less.Because of the domestic use of flexible suspension test cases are relatively few,most laboratories do not have this experience and technical accumulation.This article relies on a case study of vibration testing of finished product,describes several concerns and solutions in the implementation process,and compares the measurement points on the finished product during the experiment with the measured data,for the difference,also gives the influence of the working condition action on the measured data,demonstrates the test objective of simulating the actual installation state,and prospects the development of vibration testing using actual data induction spectrum.
