根据陀螺运动方程,推导出了压电振动陀螺的近似等效电路,并加以演化来处理由压电陶瓷与谐振器表面粘接时切变引起的附加力的影响。提出了降低该影响的新电路。 计算了陀螺特性并经实验作了检验。亦表明,外加角速率的判断不仅可通过测量输出幅度还可通过测量其相移来完成。 According to the gyroscopic equation of motion, the approximate equivalent circuit of the piezoelectric vibrating gyroscope is deduced and evolved to deal with the influence of the additional force caused by the shear bond between the piezoelectric ceramic and the resonator surface. A new circuit that reduces this effect is proposed. The gyroscopic characteristics were calculated and tested experimentally. It also shows that the judgment of the applied angular velocity can be accomplished not only by measuring the output amplitude but also by measuring its phase shift.
