Abstract	In this paper, a two-degrees-of-freedom model with two coupled oscillators is established to study the dynamics of quartz tuning fork force sensors. Air squeeze-film damping is considered in this model. When the laser power is 40 mW and the distance between the tuning fork and detected objects is approximately 0.5 m, the resonance amplitude of the tuning fork under the electromagnetic radiation pressure of the laser can reach 0.22 pm. Electromagnetic radiation pressure and resonance amplitude have the tendency to exponentially decay along with the distance between the tuning fork and detected objects. The influence of laser power and distance between the tuning fork and detected objects on electromagnetic radiation pressure is also considered. Lastly, an experimental device is set up to verify the calculation result of the model. Analysis shows that the experimental data are in good agreement with the theoretical calculation results.
