Problems solved by technology

Any change in the angular momentum of any part of the spacecraft will bring disturbance to the entire platform. The light one will affect the attitude stability accuracy of the satellite platform, thereby reducing the performance of the entire satellite. The severe one will have a serious impact on the satellite attitude and orbit, and ultimately affect the entire platform. Completion of satellite functions and tasks

Abstract

The invention relates to a device and a method for testing the wire-wound moment of a rotary table. The device for testing the wire-wound moment of the rotary table comprises a rotating platform, a rate gyroscope, a B code, a rotating platform driving unit and a data processing computer, wherein the rotating platform and the B code are electrically connected with the data processing computer respectively; the rotating platform driving unit drives the rotating platform to rotate; and a rotating component to be tested and the rate gyroscope are arranged on the rotating platform, and the rotating component to be tested, the rate gyroscope and the rotating platform rotate synchronously. The device for testing the wire-round moment of the rotary table is simple in structure, and the device and the method for testing the wire-round moment of the rotary table are high in testing accuracy and convenient to operate.

Description

technical field [0001] The invention belongs to the field of optics, and relates to a torque test device and a test method, in particular to a turntable wire winding torque test device and a test method. Background technique [0002] Winding torque: the disturbance torque that affects the rotation of the turntable caused by the tension exerted by the power line and signal line on the turntable. The winding torque will not only affect the precision and stability of the turntable movement, but also cause the turntable to stall in severe cases. Therefore, the wire winding torque is a very important technical parameter like the friction torque, and the influence of the wire winding torque must be taken into consideration when selecting the drive motor and debugging the control parameters. [0003] The influence of wire winding torque on rotating parts in space: the orbiting spacecraft is in a space microgravity environment, and it is an independent system externally. The entire...
