【Abstract】 With the resurgence of lunar exploration, establishing sustainable early-stage infrastructure capable of withstanding extreme lunar conditions has become a critical prerequisite for long-term lunar settlements. This study proposes an innovative foldable pyramid-shaped hybrid lunar structure, designed as a primary parking and protection facility for mission assets(e.g., rovers, habitation modules) during the initial phase of lunar missions. The structural configuration draws inspiration from pyramid-shaped camping tents, featuring exceptional stability and space efficiency. The core design integrates three functional layers: a foldable internal frame made of aluminum alloy T6-7075, a flexible Kevlar-49 envelope, and an in-situ lunar regolith shielding layer, leveraging In Situ Resource Utilization(ISRU) to minimize launch mass and enhance cost-effectiveness. The modular internal frame consists of four central main rods connected by long hinge straps, paired with diagonal secondary support rods to ensure uniform load distribution. The Kevlar-49 envelope serves as an airtight barrier, with a sophisticated folding mechanism that enables a high volume compression ratio of 1:4, facilitating compact storage during launch and synchronized deployment with the frame on the lunar surface. The deployment process involves two controlled phases: retraction of external rods for transport and sequential extension guided by hinges to form the complete pyramid geometry, ensuring wrinkle-free coverage of the internal frame by the Kevlar membrane. Compared with existing rigid and inflatable lunar structures, this hybrid design integrates the advantages of portability(high compression ratio) and robustness(superior radiation, thermal, and micrometeorite protection). Key innovations include the pyramid configuration with efficient space utilization, a thermomechanical analysis model for performance prediction, and the synergistic materials application. The structure effectively shields against extreme temperatures, intense radiation, and micrometeorite impacts, providing a stable platform for early lunar operations.To validate structural performance, comprehensive thermal and solid mechanics simulations were conducted, employing the Finite Element Method(FEM). Thermal analysis focused on temperature distribution and variations across a lunar day under different solar elevation angles. Results indicated that while the outer surface of the structure experienced extreme temperature fluctuations from 113 K(night) to 397 K(daytime), the internal thermal environment remained stable, demonstrating the regolith’s superior thermal insulation capability attributed to its ultra-low thermal conductivity. The surface temperature distribution and variations across a lunar day at different solar elevation angles are explained to demonstrate the thermal behavior of the structure. Mechanical simulations optimized the Kevlar layer thickness and evaluated the load-bearing capacity of the aluminum frame. The internal frame exhibited exceptional load-bearing capacity under different boundary loads.Future research will focus on material durability under combined lunar environmental stresses(radiation, thermal cycling, lunar dust abrasion), geometric optimization of asymmetric pyramid configurations for different lunar latitudes, development of intelligent monitoring and in-situ repair systems, and ground validation tests using lunar environment simulators. This study offers a resource-efficient, deployable solution for early lunar infrastructure, laying a solid foundation for future lunar exploration and settlement.
