| 摘 要： | By analyzing the correlation between modal calculations and modal experiments of a typical support-er, an effeetive finite element analysis(FEA) model of the aetual aerospaee supporter is ereated. According to the analysis of eonstrained viseoelastic damping, the strategies of PVC have been worked out, and the correlation between modal ealculations and modal experiments of the supporter has also been eomputed, and then, an experiment has been designed based on the ealculation results. The results of experiments verify thai the PVCstrategy can effectively suppress vibration.

| Abstract: | 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. |
