Problems solved by technology

The outstanding disadvantages of these old-fashioned angular rate gyroscopes in practical applications are: large size, high price, easy damage, low impact acceleration resistance, short life, small measurement range (the maximum measured value of the old-fashioned angular rate gyroscope is only 500), frequency response Low (up to 100Hz) and many do not have self-test (sel f-Test) functions, etc., even today's more advanced fiber optic or laser gyroscopes are difficult to obtain widely because of their high price and large size. application

Abstract

The invention discloses a liquid floating type angular rate gyroscope detecting device, which relates to the technical field of inertial measurement. The device includes a motor, a buoy, an amplifier,an annunciator, a torque device and a housing, with the housing and the buoy being filled with liquid, and the buoy being suspended in the housing. The motor is disposed in the buoy and is connectedto the inner wall of the buoy through a bearing. One end of the buoy is fixedly connected to a stator of the annunciator, and the other end is fixedly connected to a stator of the torque device. The annunciator and the torque device are connected to the inner wall of the housing through bearings. The annunciator is electrically connected to the motor, and sends output current signals of the motorto the amplifier. The amplifier sends the output signals to the torque device after amplification of the output current signals. The motor is used for generating gyroscope torque. The torque device isused for generating feedback torque balancing the gyroscope torque. The device is simple in structure, low in construction cost, and high in reliability and has a self-detecting function.

Description

technical field [0001] The invention relates to the technical field of inertial measurement, in particular to a detection device for a liquid-floating angular rate gyroscope. Background technique [0002] At present, most of the angular rate gyroscopes commonly used in missile control, geological survey, industrial control, aviation vehicle stability control, strapdown inertial navigation, automotive autopilot and robot control are mechanical. , such as liquid floating or semi-liquid floating, flexible angular rate gyroscope with rotating motor, etc. The outstanding disadvantages of these old-fashioned angular rate gyroscopes in practical applications are: large size, high price, easy damage, low impact acceleration resistance, short life, small measurement range (the maximum measured value of the old-fashioned angular rate gyroscope is only 500), frequency response Low (up to 100Hz) and many do not have self-test (sel f-Test) functions, etc., even today's more advanced fib...
