Abstract

With the great improvement of the performance of modern aircraft , the aviation airborne integrated equipment rack has to withstand a very harsh mechanical environment under the condition of strict weight restriction, aiming at the fatigue failure of a rigid connection equipment rack in the durable vibration test. combined with the actual anti-vibration urgent needs to carry out vibration isolation design research, how to reasonably select the vibration isolator is the most core key technology. This paper systematically expounds the complete process and process of vibration isolation design based on theoretical calculation, simulation analysis and experimental verification, which is different from the previous empirical design, and establishes a forward vibration isolation design method based on the active requirements of the product itself for the performance parameters of the vibration isolator. the target frequency of the vibration isolation system and the key parameters of the vibration isolator are theoretically analyzed and calculated, and the selection of the vibration isolator is determined. Further simulation analysis and experimental verification are carried out. The results show that according to this vibration isolation design method, the vibration isolation effect of vibration isolator selection is obvious, the overall vibration isolation efficiency is more than 55%, the theoretical calculation and simulation analysis are accurate, and the test passes smoothly. It verifies the rationality and effectiveness of the forward vibration isolation design flow in a strong vibration environment, and has important practical significance and broad application prospects.
