Research on Control Error Optimization Method of Random Vibration Test of Hydraulic Shaking Table Based on Model Simulation
With the vigorous development of national defense construction,the requirements for electronic equipment are becoming more and more stringent.In order to eliminate the interference caused by the high-frequency energy signal of the electronic equipment in the vibration test to the high-frequency interval of the vibration control signal(10～200)Hz,the control error of the vibration test exceeds the required value.Based on the multi-factor analysis of the vibration table and other mechanical and physical parts in the test process,this paper analyzes the causes of vibration control overerror,and finally finds that reducing vibration error by optimizing the model simulation control algorithm of the hydraulic table is the key to control error[1].The error value can be reduced to less than 10%of the compliance,and the empirical results obtained through this analysis can bring enormous economic and technical benefits for test production and scientific research and development.
