This paper presents a dynamic calibrating device of force sensor. This device is used for the dynamic calibration of force sensor when the force is loaded more and more incessantly to the force sensor which is being calibrated. This device is motivated by the moment electromotor, and enhances the force which is produced by the moment electromotor through a ball screw and two hydraulic cylinders. In this way, it comes true that a big loading output is produced on the condition that the device is portable with micro-drive. Then ANSYS is used to analyze the stiffness and intensity of the structure which is designed, the result of which shows that the mechanical structure is reasonable. Finally, a tentative exploration about the data collection and manipulative system of the dynamic calibrating device is made.
