Research on vibration transmissibility calculation model for airborne electronic equipment
In order to solve the problem of the accuracy of the random vibration transmissibility calculation of airborne electronic equipment, the basic STEINBERG sinusoidal vibration transmissibility model and the IRVINE random vibration transmissibility model were firstly verified through tests, and it was found that there was room for improvement in the accuracy of the IRVINE random vibration transmissibility model. Therefore, on the basis of the "Three-interval method", the effects of and transient acceleration of random vibration were taken into consideration, and a more comprehensive "Five-interval method" was proposed; then, the structural fatigue coefficients of the model were corrected by combining with the characteristics of the airborne electronic equipments. The results show that the error between the proposed random vibration transmissibility calculation model and the measured value is less than 5%, which is closer to the measured value, proving that the proposed model is more accurate.
