Margin-of-Safety Analysis on Composite Structure of Space Detector Based on Finite Element Method
摘要
Abstract
A margin-of-safety(MS)analysis method based on the finite element method is proposed to predict the strength and MS of composite structures.The MS of the composite substructure of China's Mars orbiter is analyzed by means of the ABAQUS software and the secondary development pre/post-processing program of Python.The accuracy and reliability of the MS analysis method are verified by the test results.The analysis results show that the main structure of China's Mars orbiter is reinforced locally,and thus the stiffness,strength,and MS of the structure are improved.关键词
