Rockets Elastic Static And Dynamic Strength Analysis

In this paper, the Finite Element Method(FEM) is used in the analysis of the static and dynamic strength of solid rocket engine. In the analysis I-deas Master Series 8.0 program is used.The static strength analysis models of combustion chambers, nozzle , plate closure are established , and the stress and displacement of them are calculated . The thermal field and thermal stress of chambers are calculated by the FEM ,and the temperature-position curves are given.Moreover , the structural dynamics analysis models of wing and the whole rocket are established , and the vibration modes are evaluation .This paper provides a new methods of analyzing strength of solid rocket engine . And many value materials are given so that the designers of solid rocket can improve their structure design .
