Abstract: With the weight and thickness limits in practical application as constraint conditions, the damping structure was designed and the specimen prepared according to the constrained damping structure design theory. The first five natural frequencies and modal damping rations of the specimens were identified after the vibration test, and the influences of material parameters of damping layer, material parameters of constraint layer and damping structure form on damping performances of constrained damping structure were analyzed.
