摘要
文章介绍了形状记忆合金(SMA)的一种本构关系和一种简单实用的回复力模型及其回复力公式 ,并对SMA复合梁的减振机理进行了分析和推导。试验结果表明 ,SMA具有较好的减振效果 ,是一种优质的减振材料。
One of the constitutive relations of SMA and a simplified and practical model of restoring force,including its formula are introduced in this paper.And damping mechanismof SMA composite beamis studied and deduced.The experimental result shows that SMA is a quality damping material and possesses preferable damping capacity.
