Vibration analysis and structural optimization of multifunctional structures on airborne electronic equipment

The finite element method was utilized in this paper to analyze multifunctional structures on airborne electronic equipment. The results of this analysis show that the strengthened tendons can improve the inherent frequency of the structure, the density of screws arrangement can also affect its inherent frequency, and the circuit of elements should be placed symmetrically. Finally a new type of multifunctional structure with high inherent frequency was designed which had a better anti-vibration performance than the old one.
