Problems solved by technology

Although this method can reduce the influence of parameter errors on navigation accuracy, it must use a three-axis turntable for testing, so the equipment is complex and the requirements for experimental operations are relatively high. In the experiment, first determine the angle value that needs to be turned, and input the three-axis The turntable, then, adjust the tilt angle of the gyroscope according to the given angle value, and control the inner frame of the turntable to stop and

Example Embodiment

[0031] Such as figure 2 As shown, the present invention is composed of a hexahedral frame 1, a rear clamping strip 2, a bottom clamping strip 3, a seat plate 4, a pressing plate 5, a large cushion block 6, and a small cushion block 7. The hexahedral frame 1 is placed on the surface of the turntable water platform, and the hexahedral frame 1 Provide a support for the rear clamping strip 2 and the bottom clamping strip 3. The two sets of clamping strips provide a restraining force for the seat board 4 in space, clamp the seat board 4 and fix it at a certain inclination angle. Such as Picture 11 As shown, no matter whether the thickness of the pressure resistance part of the gyroscope is large or small, as long as you select a block with the same thickness, the gyroscope can be pressed tightly with the pressure plate 5 and fixed on the seat plate 4 to keep the gyroscope in space. A fixed tilt angle, accurately measure this angle, and then use a single-axis rate turntable to provide...

Abstract

This invention puts forward an uncoupling test device for the scale factor and input shaft distortion angle of a gyro including a hexahedron frame, a holding strip, a baseplate and a holding down plate, in which, the hexahedron frame supports the holding strip, which restricts the baseplate, the gyro tilts to a certain angle along with the baseplate and 8 accurate location bolts are set on the baseplate, a test device is set on the level mesa of a single shaft rate swing table to provide an input angle velocity, the value of the tilted angle is got by testing the distance from the location bolt to the swing table mesa by a test device to uncouple the parameters based on the computation model.

Description

technical field [0001] The invention relates to a decoupling test device for a gyroscope scale factor and an input shaft misalignment angle, which belongs to the testing, calibration and compensation technology of micro-miniature, low-cost and low-precision inertial measurement devices in the technical field of navigation, guidance and control. Background technique [0002] In the process of inertial navigation, the error caused by inertial devices usually accounts for more than 70% of the entire guidance error, which leads to higher and higher requirements for inertial devices. By improving the processing technology, the precision of the inertial device can be improved, but the cost is huge. The inertial navigation test technology is a new discipline developed on the basis of the inertial navigation technology. People strive to accurately evaluate its performance, accurately test the relevant parameters, and pass Error compensation measures are used to improve the performan...
