“Ask Tian” spreads its “big wings”, and the anti-vibration technology is really strong!
On the 6th August 2022 … After two months of trip or two months into a six months mission on the China Space Station after the docking of the Wentian Experimental Cabin Module….. The Shenzhou 14 crew Takionaut has not finished unpacking the courier packages of the all new Wentian Experimental Cabin Module… Today this week it’s been the very “busiest space Takionaut trio” continued to organize onboard supplies for 5.5 hours.
Technical staff from the Fifth Academy of Aerospace reduce the impact of the vibration of the flexible solar panels on the rendezvous and docking tasks .
The “flexible” feature of the flexible solar panel determines that it is particularly easy to vibrate. If the control is not good, each “gentle vibration” may have a fatal impact on the space mission. To this end, on the basis of the semi-rigid solar panel control of the Fifth Academy of Aerospace Science and Technology Group, 502 has developed a method to suppress the vibration of flexible solar panels, and use the method of “four ounces” to make them “fly smoothly” in space.
Previously, most of my country’s spacecraft used semi-rigid solar panels. The core module of the space station launched in 2021 used flexible solar panels for the first time. Compared with the two, the semi-rigid solar panel has a narrow natural frequency range, and the algorithm is simple and easy to control, while the flexible solar panel is too soft and has a wide natural frequency range. The same control frequency on the spacecraft coincides with its natural frequency. , the windsurfing board will be excited and vibrated .
If this vibration is allowed to develop, it will affect the control accuracy and stability of the spacecraft , thereby affecting the load work and the rendezvous and docking. More importantly, if the control system is not specially designed, it may stimulate the control system to respond passively , resulting in a situation in which the more control, the more severe the vibration, the more severe the vibration, the more the control system needs to control, which in turn makes the system unstable and affects the space station. The track runs stably.
This is like two people carrying water with a pole, one can carry it, and the other can’t carry it. Those who can carry water can adjust the frequency and amplitude of the ups and downs of the body to make the pole on the shoulders vibrate very little, and control the water in the bucket to only have tiny ripples, and at the same time walk like a fly . People who can’t carry water will not control the pole by adjusting their body, which will cause the pole to shake up and down seriously, the bucket shakes violently, and the walking speed is also affected by the pole, which makes it faster and slower. There was less than half a bucket of water left.
The experts of the Aerospace Science and Technology Group use a similar method to suppress the vibration through the attitude adjustment of the spacecraft. The adjustment range may be small, but it is very useful.
As the so-called “knowing is not difficult, doing it is difficult”, the realization of the suppression of the vibration of the large flexible windsurfing board of the space station is inseparable from the research and development of the researchers for several years. They first identified the source of the vibration of the windsurfing board through theoretical analysis and experiments, and then found a way to control the source. Through fine mathematical simulation and a large number of physical simulations, they summarized and designed an effective algorithm for controlling the vibration of the solar windsurfing board. , the algorithm is the core technology to suppress the vibration of solar panels .
The basic process of its control is to first identify the vibration parameters of the flexible solar panel by means of camera observation, and then the computer determines the attitude adjustment that the spacecraft needs to make through the corresponding algorithm, and issues commands to the person responsible for adjusting the spacecraft attitude. Executive body. Although the developers have little knowledge of the technical details of suppressing the vibration of solar panels abroad, from the perspective of control effects, the control method of our independent innovation design is not only more suitable for the “physique” of Chinese spacecraft, but the main technical indicators are even better than those of foreign countries .
No matter how big or small, it must be considered, designed and verified. This is the characteristic of aerospace engineering. To build the Chinese’s own space station, the Chinese want to go deeper into the deep space and promote the building of a space powerhouse. Astronauts are making progress every day in the process of solving such large and small problems.
