|
| () |
| Abstract: |
| The response mean square of absolute displacement and acceleration is calculated for the vibration isolation system of airborne electronic equipment undergoing random vibration. By comprehensive consideration of the effect of these response values, the free frequency of system is determined. An application example of project is given to prove the feasibility of this method. |
| Key words: airborne electronic equipment random vibration vibration isolation system free frequency |
