Application of FEA in structure optimization of load-bearing frame of propulsion system test-bed for large-thrust rockets
摘要
Abstract
The FEA software ANSYS is used in this study to construct the finite element model of the load-bearing frame of a certain propulsion system test-bed,and analyze the stess distribution of the load-bearing frame under the test and ready-tested status.The structure and layout of the loadbearing beam are optimized according to the results of stress analysis to make the strength of the model meet the working requirements.The stress analysis and optimization are also made on the legs of the load-bearing ring,part of the frame.The mode of the frame is studied at last.Its axial first-order mode is within the range of the axial first-order mode of UUT,so further measures should be taken to avoid resonance.关键词
