摘要
本文导出了粘弹性非约束阻尼层结构的阻尼层厚度与降噪量的关系,并进行了试验验证。指出在以降噪为目的对结构进行阻尼处理时,不能以结构损耗因子作为设计指标确定其厚度参数,而应以降噪量为指标。
The relationship between thickness of viscoelastically free damping layer structure and amount of noise reduction has been derived in this paper,and the experiment verification has also been carried out.It is pointed out which thickness of damping layer,when noise reduction treated by damping,is given the amount of noise reduction rather than the loss factor.
