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.
