Abstract
The vibration environmental validation of aerospace electric equipment includes FEM analysis in the stage of design and vibration test in the phase of experiment. The partial enhancement is usually used to increase local stiffness and decrease acceleration response which is beyond the demand in the analysis. But sometimes, this measure does not work well. In this paper, a new method to decrease acceleration response is used from energy dissipation point of view. AS the whole energy of vibration is certain, if the subordinate structure expends more energy via diminishable stiffness, the energy on PCB will be reduced with less weight and acceleration response. A representative structure's acceleration response was analyzed with both partial enhancement method and energy dissipation method. The result shows that acceleration response increases 0. 9% with the former and decreases 29% with the latter.关键词
