Abstract

The embodiment of the invention discloses a double-shaft rotary table system. The double-shaft rotary table system comprises an inner shaft part and an outer shaft part, wherein the axial direction ofthe inner shaft part is orthogonal to the axial direction of the outer shaft part, and the outer shaft part is in shaft connection with the inner shaft part, so that the inner shaft part can rotate around the axial direction of the outer shaft part. The double-shaft rotary table system belongs to a horizontal T-shaped structure double-shaft rotary table. A control host outputs high-precision driving signals conforming to motor operation characteristics to an inner shaft motor and an outer shaft motor, the inner shaft motor and the outer shaft motor can respond to the driving signals of the control host to smoothly rotate according to a set operation curve, and smooth transition between different rotating speeds is realized, so that the problem of high distortion degree of a large rotary table system in a low-speed state in the prior art is solved, and the detection precision of a to-be-detected device is improved. Meanwhile, the double-shaft rotary table system provided by the embodiment of the invention has the advantages of small size and light weight, and can meet the verification requirements of various engineering levels.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of simulation control, in particular to a dual-axis turntable system. Background technique [0002] The gyroscope is used to detect the angular velocity of the object, and the accelerometer is used to detect the acceleration of the object. In the production process of the gyroscope or the acceleration sensor, it is necessary to calibrate and repeatedly check the gyroscope or the acceleration sensor, so that the output of the gyroscope or the acceleration sensor meets the specification requirements under the action of the set input signal. [0003] The existing two-axis turntable system has a large volume, and the existing two-axis turntable system has a large velocity distortion at low speed, which affects the test accuracy and test reliability of the gyroscope or acceleration sensor at low speed. Contents of the invention [0004] An embodiment of the present invention provides a du...
