| 摘 要： | 在干式调谐挠性陀螺仪DTG**的基础上,使转子具有适当的不等转动惯量及转子的轴向摆性,可将DTG改进成一种多功能惯性敏感仪DTAG.它可以敏感正交轴向的角速度和线加速度.本文建立了DTAG的力学模型,导出了方程的稳态解.从力学分析的角度证明了DTAG实现多功能的可行性. 另外,若仅就DTG而言解决了用单环结构消除2N角振动引起常值漂移的问题.

| Abstract: | In constrast to symmetric rotor of Dry-tuned GYRO (DTG), the rotor of Dry-tuned accelerometer/GYRO (D'TAG) has different transverse moments of inertia and a proper rotor pendulosity. DTG can be improved to DATG. This instrument provides measurements of angular rate about two axes and linear accelerations along two axes. The study of DTAG is a significant effect on the development of Inertia Navegation System.This paper presents the dynamical equations of DTAG. Under the condition of multi-frequency vibration, the stationary solution is computed according to the analyses of the dynamics. The feasibility of dry-tuned sensor technology for mechanizing an inertia grade four-axes multi-function senson is demonstrated.This paper also presents the condition of eliminating error torques resulting from angular vibration inputs of double spin frequency of the driving shaft. This condition is obtained by way of simple construction of single gimbal GYRO. |
