【摘要】 分析了预应变形状记忆合金（ Ｓ Ｍ Ａ） 丝的回复应力在其树脂复合梁振动过程中产生的回复力矩，并对这种复合有预应变 Ｓ Ｍ Ａ 丝的复合结构梁在不同温度下进行了自由衰减振动实验，结果表明梁振动的对数衰减率和 Ｓ Ｍ Ａ 的回复应力有很好的对应关系．更多还原

【Abstract】 The moment arisen from the recovery stress of TiNi shape memory alloy wire embedded in the beam with initial strain during the vibration of the compound beam was analyzed, and the experiment of attenuation vibration of the beam was carried out. The good corresponding relation between the recovery of the shape memory and the rate of logarithmic attenuation was found.更多还原
