介绍了应用粘弹分析仪检测约束型层压复合钢板阻尼性能的方法.分析表明,层压复合钢板的阻尼性能取决于约束层树脂材料本身的阻尼性能,而且按一定规律随温度变化,在所用树脂材料的玻璃化转变温度附近,其阻尼因子tgδ达到最大值.
The method of viscoelasticity analysis to test the damping performance of constrained laminated steel sheets is introduced.The analysis shows that the damping property of the laminated steel sheets depends on the damping property of the constrained layer resin material itself and varies with the temperature according to a certain rule Near the glass transition temperature of the resin material, the damping factor tgδ reaches its maximum value.
