摘　　要：以某型号复合结构喷管为例和有限元法为手段，从系统工程的角度上全面地阐述和分析了火箭发动机工作过程中喷管结构变形的仿真方法及结果分析。仿真结果表明程序合理，具有应用和推广价值。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.
