Lunar landing impact simulation experimental device

Abstract

The invention discloses a lunar landing impact simulation experimental device, which comprises a base, fixed sliding rails, simulation lunar soil, a sand box, a support frame, a sliding rail fixing beam, a foot pad movable sliding rail, a balancing weight, a foot pad movable sliding rail connecting piece and a test target object, wherein the two fixed sliding rails are horizontally arranged on the base, and the sand box, which contains the simulation lunar soil, is arranged between the two fixed sliding rails; the support frame is arranged on the two fixed sliding rails and is capable of moving horizontally on the fixed sliding rails; the sliding rail fixing beam is arranged on a top transverse beam of the support frame; two bearing sliding rails are fixedly arranged on the sliding rail fixing beam; the balancing weight is arranged between the two bearing sliding rails and is in sliding connection to the two bearing sliding rail by virtue of sliding bearings; and the test target object is arranged at the lower side of the balancing weight; and the support frame moves to the upper side of the simulation lunar soil along the fixed sliding rails, the balancing weight is lifted along the foot pad movable sliding rail and is released, and the test target object freely drops along with the balancing weight along the foot pad movable sliding rail, so that a lunar landing impact simulation experiment is completed.

Description

technical field [0001] The invention relates to a spacecraft ground simulation experiment device, in particular to a lunar surface landing impact simulation experiment device. Background technique [0002] In recent years, every year, many aerospace models have quality problems due to the impact of landing, including failure of control product components caused by landing impact, structural damage caused by impact, and excessive impact that does not meet the use indicators. When dealing with these problems, due to the lack of understanding of the coupling collision mechanism under the landing impact load of the lander, the research on the impact response characteristics is still in the stage of experimentation, improvement, and retesting. The problem brought by this solution is that there is no systematic and in-depth research on the cause of the failure and the solution to the failure, and most of them stay at the appearance of the problem, which buryes hidden dangers for t...
