Summary

The paper describes soil cutting tests conducted on Tongji-1 lunar soil simulant (TJ-1 simulant) to study excavation force under various parameters. The results are compared with FEM simulations using two methods: soil cutting and blade cutting. This paper discusses the analysis of lunar soil excavation using finite element method (FEM) and physical model tests. It highlights the challenges of lunar excavation due to the Moon's unique environmental conditions and the need for accurate excavation force prediction. The study compares FEM results with experimental data and physical model tests to validate the methods. This paper investigates lunar soil-tool interaction mechanisms using FEM simulations and physical model tests. The study focuses on the applicability of FEM in simulating lunar soil excavation, examining the effects of cutting depth, blade width, rake angle, and blade arc angle. The Tongji-1 lunar soil simulant (TJ-1 simulant) is used as the test material, with its physical and mechanical properties validated against experimental data. The paper analyzes the excavation behavior of TJ-1 simulant using FEM and experimental methods. It compares excavation force curves, defo
