Vibration Suppression Analysis for Supporter with Constrained Layer Damping

摘要

By analyzing the correlation between modal calculations and modal experiments of a typical supporter, an effective finite element analysis (FEA) model of the actual aerospace supporter is created. According to the analysis of constrained viscoelastic damping, the strategies of PVC have been worked out, and the correlation between modal calculations and modal experiments of the supporter has also been computed, and then, an experiment has been designed based on the calculation results. The results of experiments verify that the PVC strategy can effectively suppress vibration.
