The invention discloses a double-degree-of-freedom sun-oriented driving device for a pico-nano satellite solar panel, and relates to the field of aerospace. A piezoelectric material-carbon fiber composite material is used as a motor stator, so that light weight is realized; two-degree-of-freedom rotation of the sailboard is achieved by installing the ultrasonic motors in the two orthogonal planes, so that the sun is tracked, and the power generation efficiency is improved. Comprising a base used for being connected with a pico-nano satellite, a solar panel supporting structure used for being connected with a solar panel and a pitch axis base connected between the base and the solar panel supporting structure. The system further comprises two ultrasonic motors, and the two ultrasonic motors are a yaw axis motor and a pitch axis motor respectively. Two-degree-of-freedom rotation of the sailboard is achieved, so that the sun is tracked, the power generation efficiency is improved, the weight of the solar sailboard device can be greatly reduced under the same energy demand, and the system structure of a pico-nano satellite is simplified.
Description
technical field [0001] The invention relates to the field of aerospace, in particular to the optimal design of the ultrasonic motor, the rational design of the structure and the application on the solar panel of the Pina satellite. Background technique [0002] The Solar Array Drive Assembly (SADA, Solar Array Drive Assembly) consists of a solar panel drive mechanism and a solar panel drive route. Its main functions are: supporting the solar panel, driving the solar panel to orient to the sun, and transmitting electric power and signals between the solar panel and the aircraft body. At present, the problems existing in the solar panel drive device are as follows: [0003] 1) At present, most of the driving devices of solar panels are large and heavy, so they cannot be used in Pina satellites. [0004] 2) The accuracy of the current solar sail panel driving device is low, which cannot meet the requirements of the Pina satellite for the stability and accuracy of the driving ...
