The invention discloses a lander foot pad impact soil mechanical property measuring device which comprises a transverse beam, guide brackets, a base, an impact hammer, a soil tank, a measuring component and a record component, wherein the transverse beam is arranged above two guide brackets, is fixedly connected with the guide brackets, and plays a role of support; the guide brackets are placed vertically, are connected with the base through bolts, play a role of support and are used as sliding guide tracks of the impact hammer; the base is used for fixing and supporting the two guide brackets; the impact hammer is mounted between two guide brackets and can slide along the guide brackets; the soil tank is positioned right below the impact hammer; the measuring component consists of a force sensor and an accelerometer, is mounted on the impact hammer, and is capable of measuring the acceleration and the stress of the impact hammer in real time in the testing process; the recording component consists of a signal processor and a computer and is capable of measuring measurement results of sensors. By adopting the device, soil is impacted by changing the counterweight and the launching height of the impact hammer, and mechanical property rules of the soil are measured according to related parameters.
Description
technical field [0001] The invention relates to a measuring device for lander foot pad impact soil mechanical properties, in particular to a method and device for obtaining the law of bearing mechanical properties of asteroid soil, belonging to the technical field of analysis and measurement control. Background technique [0002] With the rapid development of science and technology, people are no longer satisfied with the research on earth things. Exploring the origin of the universe and detecting alien planets has become a research hotspot in the scientific community today. Most of the extraterrestrial exploration missions completed by various countries use legged landers to carry detection equipment to softly land on the surface of extraterrestrial planets. Famous legged landers include America's Apollo manned lunar module, America's Viking Mars probe, and my country's Chang'e-3 lunar probe. Given the common use of legged landers, continued research on them is warranted....
