Abstract
In the design process of space science experimental equipment, in order to better grasp the dynamic characteristics of the structure, a large number of finite element analysis is needed. This paper comprehensively use HyperMesh and Nastran to establish a set of finite element analysis process for space science experimental equipment, combine the advantages of each software to perform finite element analysis comprehensively, which greatly improves the accuracy and efficiency of the finite element analysis, the problems of this kind of engineering analysis has certain reference value.
Highlights
With the further development of the manned space engineering, the research prospects for the application of space science in China have been presented to our eyes[1]
In the design process of space science experimental equipment, a large number of finite element simulation analysis are required, through finite element analysis, the designed space science experimental equipment can be optimized based on the analysis results, shortening the development cycle and saving costs[2,3]
Modal analysis is the most important one in the finite element analysis process of the space science experimental equipment, it often generates violent vibration during the spacecraft launching process, which has a huge impact on the space science experimental equipment in the spacecraft
Summary
With the further development of the manned space engineering, the research prospects for the application of space science in China have been presented to our eyes[1]. In the design process of space science experimental equipment, a large number of finite element simulation analysis are required, through finite element analysis, the designed space science experimental equipment can be optimized based on the analysis results, shortening the development cycle and saving costs[2,3]. Modal analysis is the most important one in the finite element analysis process of the space science experimental equipment, it often generates violent vibration during the spacecraft launching process, which has a huge impact on the space science experimental equipment in the spacecraft. This paper comprehensively use the different characteristics of Creo, HyperMesh and Nastran to establish a set of finite element analysis procedures, the modal analysis of the space science experimental equipment obtains its natural frequency and mode shape, which has certain reference significance
