This paper investigates the mechanical properties of irregularly shaped lunar soil simulant particles, focusing on their non-linear mechanical behavior. Experiments were conducted using a high-precision micro-operation test bed, and a contact model was developed for irregular particles, equivalent to spherical particles using piecewise function fitting. Simulations were performed in EDEM to validate the model. The paper discusses the constitutive properties of irregularly shaped lunar soil simulant particles, focusing on their mechanical behavior and modeling. It outlines the experimental methods used to study the normal mechanical properties of these particles on a high-precision micro-operation platform. The paper also presents a modeling approach to simulate the mechanical properties of irregular lunar soil particles using EDEM. The study contributes to the understanding of lunar soil simulant behavior, which is crucial for lunar base design and extraterrestrial construction.
