It is important to research the relationship on the vehicle-terramechanics in lunar surface circumstances for the lunar rover to work according to schedule. However the regolith used in the laboratory test will greatly influence the precision and reliability of the test results. The regolith research based on the data of lunar soil specimen and the JSC-1 simulant lunar soil

the eruption is used as the basic material

and some hematite were added as regulator. Parameters of simulant lunar soil were measured

such as specific gravity

angle of internal friction

cohesion

grain size distribution

and mineralogy chemical composition. The results showed that parameters of simulant lunar soil in this test were close to the parameters of the lunar soil after adjusting grain size and proportion of added hematite sands. The simulant lunar soil could be used for the basic test of the terramechanics on moon in near future.
