Single-axis sudden stop rotary table based on gyroscope characteristics

Abstract

The invention discloses a single-axis sudden stop rotary table based on gyroscope characteristics. The single-axis sudden stop rotary table comprises an X-axis system, a Y-axis system and a Z-axis system. A Y-axis torque motor assembly is installed on one side of a Y-axis left shaft, and a Y-axis horizontal angle sensor is installed on one side of a Y-axis right shaft. The top of an X-axis upper shaft is connected with a table top through a table top transition seat, an X-axis angle measuring element is installed on one side of the X-axis upper shaft, the X-axis upper shaft is connected with the Y-axis left shaft and the Y-axis right shaft through the upper portion of the frame, an X-axis outer rotor torque motor is installed on one side of an X-axis lower shaft, a photoelectric sensing piece is installed on the other side of the X-axis lower shaft, and a photoelectric sensor is installed on one side of the photoelectric sensing piece. The X-axis lower shaft is connected with a Y-axis left shaft and a Y-axis right shaft through the lower part of the frame; the Y-axis left shaft and the Y-axis right shaft are both connected with the Z-axis through a Y-axis and Z-axis connecting transition piece, and the Z-axis is provided with a gyro motor. According to the developed sudden stop rotary table, a higher dynamic index can be achieved, the sudden stop time can reach 5-10 ms and even 2 ms, and the adjacent amplitude ratio can reach 0.3.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a single-axle stop-and-turn table based on the characteristics of a gyroscope, which is used for testing the dynamic performance of a gyroscope. Background technique [0002] The sudden stop turntable is mainly used in the testing of instrument performance. During the test, the turntable suddenly stops rotating at a certain constant speed, so as to measure the dynamic characteristics of the angular rate gyroscope (or other angular rate sensors), and the sudden stop dynamic The higher the index, the better the real performance of the instrument under test can be detected. The sudden stop dynamic index of the existing sudden stop turntable is low, the oscillation period is long, and the adjacent amplitude ratio is large. Using traditional sudden stop schemes, such as rigid stoppers, electromagnetic brake mechanisms or motor self-stopping, to achieve the goal of shorter s...

Problems solved by technology

In order to test and calibrate the dynamic characteristics of the angular rate gyroscope, users hope that the sudden stop time can be 5ms~10ms or even 2ms, which is difficult to achieve in engineering based on traditional ideas.
