Abstract
With the development of global space technology, technologies of planet soil detection, sampler and return will become more and more important in the field of deep space exploration in the future. The space environment detection and sampling tasks in deep space exploration have the characteristics of high vacuum, low gravity, intense temperature change, complex composition of target materials, and limited energy and power consumption of the sampler. Therefore, in the extremely harsh space environment, the ability of the sampler to break the surface material of the celestial body directly determines the completion of the sampling task. In view of the above situation, the introduction of impact excitation in the extraterrestrial celestial sampling returning device can improve the intrusion ability of the sampling device to hard materials, and can effectively reduce the static pressure and total energy required during the drilling process, and the vibration brought by the drilling device is also It is beneficial to chip removal and troubleshooting such as card drilling, which can effectively improve the drilling and crushing efficiency of drilling and mining equipment. Therefore, impact sampling is an ideal sampling method for deep space detection.The characteristic and rock breaking mechanism of impact load are analyzed by this paper, the application status and development trend of impact drilling space sampler were investigated, the research direction and suggestion of the impact mechanism of planet soil sampler are put forward.
