Summary

This paper describes the calibration of discrete element simulation parameters for the JLU-H lunar highland simulant using physical tests and response surface methodology. The study focuses on angle of repose and DEM parameter optimization for lunar regolith simulation. The paper titled 'Discrete Element Modeling of JLU-H Lunar Highland Simulant' presents a study on the calibration of characteristic parameters for a lunar soil simulant named JLU-H. The research includes measurements of moisture content, particle size distribution, bulk density, shear modulus, Poisson's ratio, and the angle of repose. These parameters are essential for simulating the mechanical behavior of lunar soil in various engineering and scientific applications. The study also outlines the materials and methods used, including the modeling of lifting cylinders and the selection of contact models for discrete element simulations. The work is part of a broader effort to understand and replicate the properties of lunar regolith for use in space exploration and planetary science. The paper presents a study on the Jilin University Postgraduate Innovative Research Program (2023CX059) and the National Natural Science
