| Abstract: |
| An imitation method of structure deformation of nozzles, which are made of various meterials, is described in this paper. When the solid propellant rocket motor works and the imitation results are described and analysed systematically in an all-round way means of the finite element method. The imitation program with 80386 computer is successful and reasonable according to the imitation results,and which it could be avaiable to spreaded applications. |
