Summary

This paper focuses on calibrating simulation parameters for in-situ excavation of lunar highland simulant (JLU-H). It combines physical and numerical experiments to calibrate discrete element method (DEM) parameters. The study uses a dynamic-static calibration strategy, including physical experiments, particle system establishment, and response surface optimization techniques. The model's accuracy is validated with excavation and cone penetration tests, showing less than 5% error.

These URLs are formatted with query parameters, suggesting they are used to fetch specific content (e.g., figures, supplementary materials, or articles) associated with a publication. The URLs contain placeholders like `eid` (likely an article ID) and `si` (possibly supplementary information identifiers). The text does not contain any meaningful content or data that can be summarized directly, as it is primarily a list of URLs. This paper focuses on the calibration of characteristic parameters for lunar highland soil simulant, including moisture
