The multifunctional friction-wear test device for simulating the space environment comprises a load mechanism, a vacuum box, a friction force detection mechanism, an upper sample clamp, a lower sample mounting base, an ultraviolet generating device for irradiating ultraviolet for samples, a refrigerating system for decreasing temperature inside the vacuum box, a heating system for increasing the temperature inside the vacuum box and a lower sample driving system for driving the lower sample mounting base to drive a lower sample to rotate relative to an upper sample. The disadvantage that the friction-wear test of a space is comprehensively influenced by multiple factors of thespace environment in the prior art is compensated, the friction-wear condition of the material under the space environment is preferably explored, and specifically various environments, such as highvacuum, alternating temperature, heat radiation, and complex movement working conditions, such as alternating load, high and low speed and interrupt operation, of the mechanism, in the space environment can be simulated.

Description

technical field [0001] The invention relates to the field of space environment tribology, in particular to a multifunctional friction and wear test device and method for simulating a space environment. Background technique [0002] With the advancement of my country's aviation and aerospace industry, various space agencies are more and more used in space practice. Space agencies are mainly affected by environmental factors such as high vacuum, microgravity, alternating temperature, and thermal radiation for a long time during their service in space, and are in complex motion conditions such as high specific load, high and low speed, and intermittent operation, and the resulting special tribological problems. To solve the tribological problems in the space environment and develop various new space wear-resistant materials, it is necessary to conduct a large number of space tribological experiments.

AI Technical Summary

Problems solved by technology

The space environment involves various environments such as high vacuum, microgravity, alternating temperature, and thermal radiation, as well as complex motion conditions such as alternating loads, high and low speeds, and intermittent operation. Due to many factors involved, the previous space testing machines often Development and design only for one or two limited space environments cannot fully reflect the real friction and wear conditions of materials in space environments

However, to develop a space friction and wear testing machine that is comprehensively affected by multiple factors in the space environment, many key technologies must be broken through, and the cost is high.
