Calibration device for attitude indicator

Abstract

The invention discloses a calibration device for an attitude indicator. The calibration device comprises a workbench 1, an attitude indicator 2, a rotary bracket 3, a rotary central spindle 4, a control box 5, a desk frame 6, an adjusting screw 7, an electric cylinder 8, a connecting shaft 9, a bearing 10, a bracket 11, an angular displacement transmitter 12, a shaft coupling 13, a connecting rod 14, a back bearing 15, a rotating shaft 16, a support 17, a cross roller collar 18, a screw 19, a servo motor 20 and an encoder 21, wherein the servo motor and the encoder on the electric cylinder serving as a movable component drive the connecting rod to swing through the connecting shaft and the bearing so as to drive the rotating shaft to rotate; the angular displacement transmitter is coaxial with the shaft coupling and the rotating shaft and is connected with the workbench through the cross roller collar; the workbench rotates under the action of an intelligent combined unit; an attitude angle is formed by the attitude indicator on the workbench; and a control system control the rotating speeds and reciprocating rotational frequencies of the servo motor and the encoder of the electric cylinder so as to control the frequency and the rotation angle amplitude of the calibration device and achieve high calibration accuracy.

Description

technical field [0001] The invention relates to a ship model test, in particular to a performance test of a sea state measuring instrument. Background technique [0002] The correctness of the sea state detection instrument has a direct impact on the correctness of the ship model performance test. The testing instrument is a non-standard equipment and has no centralized unit of measurement. I do not know the accuracy of the testing instrument during the previous use. In order to correctly identify the accuracy of the detection instrument, a set of calibration device is required to calibrate the sea state detection instrument to determine the correctness of the detection instrument. [0003] In order to solve the above problems, the present invention provides a calibration device for calibrating the X, Y, and Z three-axis swing angles of the attitude instrument, which has good stability, convenient operation and high calibration accuracy. Contents of the invention [0004...
