基于变形镜（DM）的影响函数，采用有限元方法对波前校正过程进行了数值模拟，分析了压电陶瓷（PZT）驱动器的疲劳特性对变形镜校正能力的影响。研究结果表明，在压电陶瓷驱动器产生疲劳后，变形镜校正能力下降。待校正畸变波前的峰谷值越大或空间高频成分比例越高，变形镜在驱动器疲劳后的校正能力下降得越明显，且受前者影响更大。

Based on the influence functions of the deformable mirrors (DMs), the wavefront correction process is simulated by the finite element method and the influence of the fatigue characteristics of piezoelectric ceramics (PZT) actuators on the correction ability of DMs is analyzed. The research results show that the correction ability of DMs decreases when the phenomenon of the fatigue occurs in PZT actuators. The larger the peak-valley value of the distorted wavefront to be corrected or the higher the proportion of the spatial high-frequency components is, the more obvious of the decrease of the correction ability of DMs after the occurrence of fatigue is. In addition, the influence from the former is relatively larger.
