Abstract

The invention relates to a memory alloy planet detection lander based on a negative Poisson's ratio structure, which includes a lander main body and a buffer structure. The main body of the lander is used to accommodate the payload, and the buffer structure is connected to the side wall of the main body of the lander at equal intervals in the circumferential direction. The buffer structure includes: a mechanical leg assembly, a main shock absorber and a foot pad; the mechanical leg assembly includes a landing leg, and the landing leg is a memory alloy with a negative Poisson's ratio structure. One end of the main shock absorber is connected to the main body of the lander, and the other end is hinged to the spherical hinge at the upper end of the landing leg to form a rotation pair of the main shock absorber relative to the mechanical leg assembly. The beneficial effects of the present invention are: through the memory alloy landing support leg of negative Poisson's ratio structure and the rotation pair of the main shock absorber relative to the mechanical leg assembly, the planetary exploration lander has strong landing buffer performance, attitude control ability and shape Recoverability, and after the cushioning performance and attitude control capabilities are enhanced, the lander can also carry heavier loads.

Description

technical field [0001] The invention relates to a planetary detection lander, in particular to a memory alloy planetary detection lander based on a negative Poisson's ratio structure. Background technique [0002] With the development of science and technology, human beings have started continuous exploration activities of extraterrestrial planets. Through the detection of extraterrestrial planets, human beings can not only discover precious mineral deposits on the planets by observing the geological structure, surface shape, and surrounding environment of the planets and their satellites, laying the foundation for future resource mining, but also through the analysis of the chemical elements on the planets. Conduct sampling analysis to understand the origin, evolution and current status of galaxies, and explore the origin of life. [0003] At present, the known landing methods of landers are mainly divided into two types: "hard landing" and "soft landing". "Hard landing" ...
