材料阻尼是一种固有属性。与一般材料相比,高分子材料往往具有较大的阻尼,其阻尼系数可达0.01—10.0。利用高聚物的阻尼特性来减振,是近年来发展起来的一门新兴学科;作为一类新型阻尼材料,也是近十几年来才得到系统发展的。 结构阻尼除受阻尼材料的影响外,还同被防护结构、约束层性质、阻尼处理方式,以及这些因素间的相互影响有关,即同阻尼
Material damping is an inherent property. Compared with the general materials, polymer materials tend to have greater damping, the damping coefficient of up to 0.01-10.0. The use of polymer damping characteristics to damping, is developed in recent years, a new discipline; as a new type of damping material, but also in the last decade to get system development. In addition to the damping effect of the damping material, the structure damping is also related to the structure of the protection structure, the properties of the restraint layer, the damping treatment method and the mutual influence between these factors, namely the same damping
