摘要:

针对空间站柔性太阳翼的桅杆进行了非耦合热诱发振动分析.用有限元法计算等效温度载荷,计算在该载荷作用下引起的桅杆振动.通过自编的Python程序实现温度位移耦合分析、静力分析、线性动态分析之间的数据读取、处理和加载等操作.以多个学科的理论为依据,使用自编的有限元前后处理Python程序和Abaqus有限元软件完成桅杆的非耦合热诱发振动分析.结果表明,非耦合热诱发振动有限元分析方法具有一定的可靠性,可以为空间站太阳翼的设计分析提供参考,分析过程中计算得到的等效温度载荷可以应用于空间站某舱段及其太阳翼的振动分析.

Abstract:

Uncoupled thermally induced vibration (UTIV) was studied for the flexible solar wing of the mast of the space station. The equivalent temperature loads were calculated and used in the UTIV analysis of the mast by the finite element mothed. Python programs were used to read, process and load the data for the coupled temperaturedisplacement analysis, static analysis and linear dynamic analysis. High efficient finite element pre/postprocessing Python programs and the finite element software Abaqus were used to complete the UTIV analysis of the mast based on multiple disciplines’ theories. The analysis results prove that the UTIV finite element analysis method is reliable and the results can be used as references for the design and analysis of the solar wing of the space station. The equivalent temperature loads calculated during the analysis can be used for the vibration analysis of the cabin and solar wings of the space station.
 

Key words: solar wing, mast, thermally induced vibration, finite element method, equivalent temperature load
