Abstract: The impact effect emerged during the touch down process of space lander may influence the safety of detection equipment and the reliability of the exploration mission. The effects of soil type and compactness, footpad diameter and impact height on the impact performance of the footpad, including impact depth, peak acceleration and force are investigated. Results show that the soil type and compactness have the maximal influence on the impact depth, followed by footpad diameter, then the impact height. The model of peak impact force was established, and the square of correlation coefficient R2 was above 0.9, which verifies that the proposed model can accurately predict the footpad peak impact force.

Key words: engingeering bionics, lander foorpad, impact performance, lunar simulant, martian simulant
