Performance simulation and evaluation of integrated modular structure with Miura origami

Abstract

As a critical subsystem in space solar power stations (SSPSs), the integrated modular structure plays a pivotal role in energy collection and transmission. Consequently, the mechanical properties of the integrated modular structure, particularly those utilizing the Miura-origami (Miura-ori) pattern, are crucial to the overall performance of SSPSs. This study explores the deployment ratio and performance of a modular flat structure based on the Miura-ori SSPS concept. A comprehensive analysis of a single module and an array of multiple interconnected modules is presented, focusing on deployment ratio and performance simulation, including the geometry model, material property, and finite element model. Additionally, it evaluates the effects of various array configurations, considering factors such as stowed volume and natural modal of the array. The findings from the simulation and evaluation provide valuable insights for optimizing the design of SSPS array structures.
