Abstract

The invention discloses a space environment superspeed impact test device and method. A test space comprising a flying area and an impact area is limited in a space environment simulation container, and an electromagnet capable of generating electromagnetic force opposite to gravity on a projectile flying at a superspeed along the test space is arranged in the space environment simulation container. Before the test, the size of the magnetic field provided by the electromagnet is adjusted according to the mass and the type of the projectile, so that the gravity borne by the projectile in the flight process along the test space can be balanced, the microgravity environment in the space can be simulated in the test space, the simulation test requirement of space ultra-high-speed impact can be better met, and corresponding mechanical research can be carried out.

Description

technical field [0001] The invention relates to the technical field of ultra-high-speed impact loading tests, in particular to a space environment ultra-high-speed impact test device and method. Background technique [0002] With the continuous development of aerospace technology, human activities in space are becoming more and more frequent. In space activities, countries have sent spacecraft with different functions into space, making the amount of space debris in orbit above the earth on the rise. In this environment, when a spacecraft is orbiting above the earth, the probability of being hit by space debris is greatly increased. Generally speaking, spacecraft have few active defense capabilities and only have certain passive protection structures. Therefore, exploring the mechanical properties of materials and structures in space environments (vacuum, microgravity, ultra-low temperature) after being impacted by ultra-high speed is of great significance to guide the sel...
