Abstract
When the constraint damping structures were made by armor plate which was 8.5 mm thick-ness,rubber and aluminum honeycomb sandwich panels,the damping properties of the constraint damp-ing structures were tested by the impact test method in the temperature ranging from -20 to 40 ℃.The results show that the properties of the rubber observably influence the vibration frequencies and the structure loss factors of the constraint damping structure.Consequently designing the damping proper-ties of the constraint damping structure by changing rubber's properties is an availability test method. When the thickness of the constraint layer were 6,10 and 15 mm,the vibration frequencies and the structure loss factors of the constraint damping structure was increasing with the increasing of the thick-ness.The structure loss factor of the constraint damping structure was increasing with the increasing of the thickness of the damping layer in the range of 0.8 to 3.2 mm.关键词
