Abstract

To solve the problems in assessment and evaluation of a vehicle mounted terminal for certain equipment, the work aims to evaluate the equipment vibration performance through tests and finite element simulations. With the vibration test of a certain type of equipment vehicle mounted control terminal as an example, a finite element simulation model of the vehicle mounted terminal was established, the response of the model under conventional vibration test conditions was analyzed, and the results were compared with the vibration test to verify the effectiveness of the model. At the same time, by considering the two actual boundary conditions of the vehicle terminal, the dynamic characteristics of the vehicle mounted terminal were clarified through modal analysis, harmonic response analysis, and random vibration, guiding the optimization of vibration environment testing. The vertical load spectrum was used to analyze the vibration response of the center position on the surface of the product through the test bench and simulation model. The comparative analysis results showed an average simulation accuracy of 90.6%, which verified the effectiveness of the finite element model. By analyzing the dynamic results under two boundary conditions, it was found that the vertical excitation excited more natural frequencies, and the vibration response without guide rail constraints was more severe. The test evaluation should focus on the vertical intensity of the product and comprehensively consider the vibration under two working conditions, in order to fully understand the vibration performance of the product under different working conditions.
