Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that each soil engineering test of the existing simulated lunar soil test requires a set of special equipment, and is distributed in different places. Once the lunar soil used for the test moves, it is difficult to maintain the original state, and then cause The test is inaccurate, and the rotary drilling and impact rock breaking tests need to build additional equipment, resulting in the inconvenience of the test and the waste of materials, and then provide a comprehensive test platform and test method for lunar soil performance

Abstract

The invention discloses a lunar soil performance comprehensive test bed and test method, and relates to the field of lunar soil performance comprehensive test. The invention solves the problems that due to the fact that each soil test of an existing simulated lunar soil test needs a set of special equipment and the equipment is distributed in different places, once lunar soil for the test moves, the original state is difficult to maintain and test misalignment is caused; and the problem that due to the fact that rotary drilling and impact rock breaking tests need additional equipment, so the testing is inconvenient and material are wasted. A Y-direction horizontal movement small-thrust driving assembly is fixed to a cross beam of a rectangular steel structure frame, an X-direction horizontal movement large-thrust driving assembly is vertically erected between the two Y-direction horizontal movement small-thrust driving assemblies, and one side of a supporting frame is installed on a sliding block of the X-direction horizontal movement large-thrust driving assembly; the lower end of a rotary shaft of a rotary motor in the rotary motor box is connected with the test tool interface, and the test soil tank is positioned below the test tool interface. The test bed and the method are used for carrying out various tests in the same simulated lunar soil environment.

Description

technical field [0001] The invention relates to the field of comprehensive testing of lunar soil performance, in particular to a comprehensive testing platform and testing method for lunar soil performance. Background technique [0002] In recent years, all countries in the world have actively developed deep space exploration technology, especially the deep space exploration capability represented by lunar exploration can reflect the maturity of a country's aerospace technology and military strength, and can drive the development of a large number of related high-tech industries, indirectly generating huge economic benefits. Lunar surface sampling is an important task for lunar exploration and sample collection and return. It is necessary to conduct a large number of tests on the ground using simulated lunar soil before launch, including the exploration of simulated lunar soil properties, performance testing of sampling equipment such as drilling and impact, and lunar soil s...
