为了研究33 μ m厚疲劳铜膜的残余应变消除，采用有限元方法模拟了无约束振动处理过程。模拟了试验过程，包括疲劳和无约束振动过程。对原始试件的疲劳过程和损伤试件的振动过程分别进行了静态和瞬态动力学分析。模拟结果表明，无约束振动处理可使疲劳铜膜的残余应变减小并重新分布。通过不同的疲劳试验和无约束振动处理，分析了振动参数对处理效果的影响，结果表明，有限元模拟结果与试验结果吻合较好。
In this paper, in order to investigate the residual strain relief in the fatigued copper film with a thickness of 33 urn, an unconstraint vibration treatment process was simulated by finite element (FE) method. The experimental processes, including fatigue and unconstraint vibration processes, were simulated. The fatigue process for the original specimen and the vibration process for the damaged specimen were analyzed by the static and transient dynamic analysis, respectively. The simulation results showed that the unconstraint vibration treatment can lead to the residual strain of the fatigued copper film to be reduced and redistributed. The effect of the vibration parameters on the treatment effectiveness was analyzed by the different fatigue experiments and unconstraint vibration treatments, and the results showed that the FE simulation results are in agreement with the experimental observations.
