A method for protecting radio-electronic devices from dynamic effects
Abstract
A multilayer-plate protection structure for a small (in dimensions and mass) analog-digital converter installed on an aircraft is detailed. Vibrational strengths and resonator frequencies of major mounting and device components were experimentally determined. A protection structure was manufactured which consists of three brass plates 0.5 mm thick and polymer compound layers 1.5-2 mm thick; the samples were cured at 120 C for 8 hours. The resonant frequency of the structure is 90 Hz, as compared to 500 Hz for a textolite plate; vibrational isolation begins at 170 Hz. No failures of instrumentation were observed during testing with the proposed structure.
