卫星蜂窝夹层结构跨尺度强度分析
Research on Cross-scale Intensity of Satellite Honeycomb Sandwich Structures
摘要
Abstract
To further enhance the precision of satellite structural design,this paper investigates multiple failure modes of honeycomb sandwich structures.A mesoscopic finite element model with embedded inserts,honeycomb cores,and other key components is developed for typical sat-ellite honeycomb sandwich structures with inserts.Three failure modes are simulated,and the corresponding critical loads are derived.Taking a camera-equipped satellite as the study case,a cross-scale modeling approach that integrates macroscopic and mesoscopic analyses is proposed.Intensity analysis results show that the maximum von Mises stress in the aluminum honeycomb lattice near the camera mounting foot reached 312MPa,which exceeds the material yield strength,thus revealing the damage mechanisms of the honeycomb core.The proposed method overcomes the issue of low analysis accuracy in conventional macroscopic modeling approaches.This study provides a reference for intensity analysis of high load-bearing satellite structures and promotes the lightweight design of satellite structures on the premise of ensuring structural safety.关键词
