| Abstract: | In the process of SRM(Solid Rocket Motor) grain configuration design,high loading fraction always gives rise to high stress and strain in the grain,and the structure integrity of grain turns hard to satisfy.To solve this problem,the integration of GA(Genetic Algorithm) and parameterized modeling method was applied to shape the optimization of the wheel shape grain.Parameterized finite element analysis model was constructed by PCL(Patran Command Language),the secondary development tool of MSC.Patran.Based on... |
