The design of a low frequency calibration shaking table is introduced in this paper. First, we confirm the design specification of low frequency calibration environment of vibration specification, we choose shaking sensor. Then, the design of the relative velocity feedback analyzes this method in detail and carry out the simulation table according to the national standard and the deployment a vibration exciter is introduced. According to the design method as the control method of the shaking table. We did simulation and calculation. Finally, we test the amplitude versus frequency response characteristics and distortion under the situation of open loop and closed loop. The results show that the low frequency movement signal of low frequency shaking table is improved and it can meet the requirement of the calibration of low frequency vibration sensor.
