In order to better optimize the performance of FSAE racing frame,a three-dimensionalmodel of frame was built by using Solidworks software,finite element analysis was pre-treated in HyperMesh,and then static stress analysis and modal analysis were carried out in Nastran.The framestructure was optimized and evaluated firstly in BEAM unit of finite element models,and then theframe of the three-dimensional geometry optimization model was modified,which above saved time ofreanalysis during modifying three-dimensional model of frame optimization,shortened the period ofstudy and exploration and improve the efficiency,.The results have great signification to optimize thecar frame.
