Description
Technical Field
The invention relates to the field related to aerospace material exposure, in particular to a steel belt driving mechanism for optical inspection outside a material cabin and an exposure platform.
Background
In space science research, the use of various materials, particularly new materials, is not isolated. The material space environment exposure experiment aims at researching the service behavior of the material under the action of space special environment effect.
Therefore, how to realize a material extravehicular exposure platform which can provide conditions for the on-rail exposure of materials, provide conditions for the on-rail motion of an optical imaging inspection module and realize the on-rail detection in a special and complicated space in a material extravehicular exposure experiment is an important problem to be solved at present.
Furthermore, in a motion mechanism applied to a space environment, compared with a mechanism working on the ground, the working difference of the space mechanism is mainly caused by the space environment, and the space dynamic environment is different from the ground environment. The influence of the space environment on the motion mechanism is mainly reflected in the following aspects:
(1) influence of microgravity
Because the existing spacecraft is usually installed and adjusted on the ground, namely under the action of gravity, when the spacecraft enters the space, the environment of the spacecraft is a microgravity environment, and the gravity in the installation and adjustment process can be released and deformed. The friction between the parts is reduced, the system is in a free state, and the interference from the outside is more prominent. Microgravity has less impact on typical mechanisms but more impact on some release mechanisms, such as the hold-down mechanism in a solar array.
(2) Influence of pressure difference
The influence of the pressure difference is usually 1X 10-2Pa～1×10-5Pa, and when a sealing structure exists in the spacecraft, the internal and external difference of the sealing structure is increased, so that the structure is deformed or damaged.
(3) Influence of vacuum outgassing
The adsorbed or absorbed gas exists on the surface of the material and is dissolved in the material, and the gas content is higher than 1 x 10-2Releasing is carried out under the vacuum degree of Pa, namely vacuum air outlet. The released gases re-condense on the cryogenic components, contaminating the optical lens, the sensor and the optically selective thermal control coating, resulting in reduced optical performance, increased solar absorption and increased temperature.
(4) Influence of radiation heat transfer
In a vacuum environment, radiative heat transfer is the primary form of heat transfer from the spacecraft to the environment. Thus, the radiative properties of the surface material have a significant impact on the thermal control function. When each system and mechanism of the spacecraft cannot work in a reasonable temperature range, the structural parts can generate stress, deformation and even fracture due to the change of the environmental temperature, so that the mechanism of the spacecraft is damaged.
(5) Effects of adhesion and Cold welding
Adhesion and cold welding typically occur at a pressure of 1X 10-7And Pa or above. On the ground, the solid surface always adsorbs organic and other films, which are called boundary lubrication lubricants, which function to reduce the friction coefficient. In a vacuum environment, a solid surface film, when partially or completely removed, forms a clean material surface between the parts in contact, and a different degree of adhesion, called sticking, occurs. If the oxide film is removed, the surface can reach atom cleanness, and can be further integrally adhered under the action of certain pressure and temperature, namely cold welding is formed.
The main method for preventing cold welding is to select mating materials which are not easy to generate cold welding, adopt solid lubrication, grease lubrication or liquid lubricant, coat material film layers which are not easy to generate cold welding and the like.
(6) Microstellar and space debris
The space environment has micro-stars and various space fragments generated by human space activities, and because the micro-stars and the space fragments have higher speed and kinetic energy, even a small fragment collides with a spacecraft, the equipment is likely to be out of order. Therefore, spacecraft should provide enhanced protection against micrometeors and space debris.
(7) Environmental impact of solar radiation
Mechanical forces are generated by mechanical structural parts due to solar radiation, and particularly, the thermal bending effect caused by uneven heating is the largest, so that the structure generates low-frequency vibration. In addition, the change of temperature has a great influence on the selection of the lubricant in the mechanism, and the lubricant with good temperature change resistance needs to be selected.
(8) Cold and black environmental impact
The cold and black environment refers to an environment in which the radiation of the sun and the spacecraft is not considered, and the heat radiation of the spacecraft is completely absorbed by the space and is not reflected. The cold and black environment easily causes the stretching performance of the retractable mechanism on the spacecraft, influences the performance of certain organic materials, causes the aging and embrittlement of the materials and the like.
The failure modes and failure mechanisms that lead to failure of the mechanism due to space environmental factors are shown in table 1.
