Method for improving photoelectric platform imaging quality through precision balancing

Abstract

The invention provides a method for improving the photoelectric platform imaging quality through precision balancing, and belongs to the field of photoelectric technologies. To improve the channel for improving the balancing precision of a photoelectric platform, the method includes the steps that 1, after the photoelectric platform is installed, a servo drive motor is removed; 2, the bearing pretightening force is lowered, and a bearing is cleaned; 3, various wires of the effective load are removed, and the resisting moment generated between the effective load and an outer frame due to wire drag is prevented effectively; 4, balancing is conducted through a traditional method of centroid balancing introduced in a background technology; 5, the bearing pretightening force is added, the servo drive motor is installed, various wires are inserted and bounded, and precision balancing is finished. By means of the method, balancing resistance moment brought out by various friction force and wire drag is eliminated, compared with a conventional balancing method, the balancing accuracy is improved, the possibility that linear vibration of the photoelectric platform is converted into angular vibration is lowered, the visual axis stabilization accuracy of the photoelectric platform is improved, and the imaging quality and operating range of the photoelectric platform are improved beneficially.

Description

technical field [0001] The invention relates to the precise balance technology of payloads in the frame of an optoelectronic platform, and belongs to the field of optoelectronic technology. Background technique [0002] With the gradual increase in the requirements for working distance and image detail resolution, optoelectronic platforms are increasingly inclined to adopt long focal length optical systems. The longer the focal length of the optical system, the easier it is to be disturbed by the vibration of the carrier and the airflow, which will cause the image to shake and blur. [0003] The disturbance transmitted from the carrier aircraft to the optoelectronic platform is divided into rotation and translation. The translation has little effect on the imaging quality of the optoelectronic platform, and the rotation seriously affects the imaging quality of the optoelectronic platform. High-frequency translation is linear vibration or linear oscillation, and high-frequen...

Problems solved by technology

[0032] The traditional trimming step is carried out after the servo motor and bearings are installed, and the various wires of the platform are plugged in. The static friction of the servo drive motor is caused by the friction between the mover and the rotor, and between the brush and the commutator, which is difficult to eliminate. ; The static friction of the bearing comes from between the ball and the raceway, which is also difficult to eliminate; the resistance moment of the wire winding is related to the stiffness of the wire, the binding method, etc.
