Based on the atomic force microscope ultrasonic excitation mode vibration behavior of the use of ANSYS modal analysis,and the combination of experiment on the cantilever probe vibration effect to the image quality were studied,the experimental results show that: the ultrasonic excitation vibration if close to or equal to the cantilever beam natural frequency or low frequency condition,the resolution of the image will be there was a significant decrease in amplitude,but also has the very big deviation.Therefore,in the course of the experiment,to avoid the cantilever beam natural frequency,can improve the imaging quality.
