论文摘要
考虑到探针和样品之间的非线性相互作用力，研究了AFM的动态行为。用第三度多项式模拟微束自由端的施加力。研究了某些参数对AFM动力学的影响。结果表明，在样品和悬臂振动的情况下，AFM的频率响应对尖端质量不敏感。在同相和抗相振动的情况下，研究了样品振动的影响。结果表明，尽管样品的振动幅度与悬臂的振幅相比非常小，但它对悬臂的谐振频率具有很大影响。
The dynamic behavior of AFM is studied taking into account the nonlinear interaction forces between probe and sample. The exerted forces on the free end of micro-beam are simulated with the third degree polynomial. The effect of some parameters on the dynamics of AFM is studied. The results show that the frequency response of AFM is not sensitive to the tip mass in the case of both the sample and cantilever vibration. The effect of sample vibration is studied in the case of in-phase and anti-phase vibration. The results show that although the vibration amplitude of sample is very small compared to the amplitude of cantilever, it has great effect on the resonant frequency of the cantilever.
