Two methods were compared with the finite element method and experiment. It proved that method based on large deflection was reasonable and effective. It can provide initial parameters for the design of SMA actuator.

• 与相关研究中采用的将挠度曲线假设为圆弧的方法进行了对比,通过有限元方法和实验进行了验证,结果表明,基于大挠度理论的研究方法更为合理有效,并且这种方法还可以为SMA驱动器的设计提供初始参数。
