摘要：
A novel long-stroke horizontal electromagnetic vibrator with maximum stroke of 1 m is proposed. To reply to the strong nonlinearity arising from long stroke, a closed double-magnetic circuit with optimal air gap, an electro-viscoelastic-suspension device and a track following device are adopted in the vibrator. Also, a compact moving component with a higher first-order natural frequency is designed to increase the operating frequency of the vibrator. Finally, experimental results show that the vibrator could output low distortion acceleration on its working platform from 0.002 Hz to 100 Hz, which verifies the validity of the proposed technologies and the applicability of the vibrator for an ultralow-frequency vibration calibration system.
