【摘要】 既能感测载体的角运动,又能感测其线加速度的多功能惯性器件是惯性技术界十分感兴趣的。对于大角速率动调陀螺仪,若把压电敏感元件安装在陀螺仪限动器上,可构成大角速率多功能惯性器件。利用大角速率动调陀螺仪陀螺电机中特有的信号检测线圈,便于加速度信号的拾取。该文介绍了器件的工作原理、信号检测与处理及在不考虑陀螺仪部分时,线加速度计的测试结果。利用两个这种器件,即可构成满足大机动捷联惯导系统要求的惯性测量部件。更多还原

【Abstract】 The multifunction inertial instrument is always held our interest It can sense angular velocity of two axis and acceleration along direction of the same two axis The new device mainly consists of dynamictuned gyro with the larger angular velocity, acceleration sensitive element and signal detecting and processing unit The accelerometer part, that is, a couple of piezoelectric crystal fixed in the gyro limiter, produces a signa1 responding to acceleration in the plane vertical to the rotor axis Just because there are the signal sense turn in the gyro motor, the acceleration signal is convenient to pick up This paper introduces the principle, the signal sense and treatment, test result of the accelerometer part without regard to the gyro part Using two multifunction inertial instrument could make up an inertial system fitting the requirements of strapdown inertial navigation system completely更多还原
