Aiming at the situation that large errors may occur when using static calibrated sensors to measure dynamic forces

a dynamic calibration device of force sensor based on horizontal sinusoidal force is designed. The dynamic force is generated by rotating eccentric. Through analysis

establish dynamics model for system. Least squares identification method is used to obtain system transfer function model parameters

and the accuracy of the model is verified under multiple sets of frequencies. Experimental results indicate that the established and identified system model can be well approximated to the actual physical system

and the model obtained by changing the parameters according to the frequency has higher precision than the fixed parameter model.
