提出了一种利用电磁力的平面振动陀螺仪，并进行了实验研究。与静电陀螺仪相比，这种陀螺仪具有制造简单和输出特性大的优点。所制造的陀螺仪包括具有两个万向节、驱动线圈和感测线圈的陀螺仪元件。驱动线圈位于外万向架下方，使陀螺仪元件振动。内万向架由于角速率的作用而产生的振动由其下方的传感线圈检测。当输出万向架以内万向架的谐振频率驱动时，可获得最大输出。测得的灵敏度为4.2至26 mV（degrees s（-1））（-1）。在几个激励电压和几个值的传感部分的气隙的灵敏度进行了测量。(C)1998年Elsevier Science S.A.
A planar vibratory gyroscope using electromagnetic force is proposed and tested. Such a gyroscope has the advantages of simple fabrication and large output characteristics compared with an electrostatic gyroscope. The fabricated gyroscope comprises a gyroscopic element with two gimbals, driving and sensing coils. The driving coils, which are under the outer gimbal, vibrate the gyroscopic element. Vibration of the inner gimbal due to an applied angular rate is detected by sensing coils underneath it. Maximum output is obtained when the output gimbal is driven at a resonance frequency of the inner gimbal. Measured sensitivities are from 4.2 to 26 mV (degrees s(-1))(-1). Sensitivities are measured at several exciting voltages and several values of the air gap of the sensing parts. (C) 1998 Elsevier Science S.A.
