摘要
针对复合材料结构强度和安全性评估问题,提出一种基于有限元法的复合材料层压板结构安全裕度(MS)分析方法。使用ABAQUS软件和Python二次开发前后处理程序,对火星环绕器复合材料结构进行安全裕度分析。通过与试验结果对比,验证了安全裕度分析方法的准确性和可靠性。根据分析结果,对火星环绕器主承力结构局部补强后,提高了结构刚度、强度和安全裕度。
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.
