Abstract:
Leakage happened to the high-pressure metal hose for several times in the hot test of a certain rocket engine. The stress distribution and bearing characteristics of the hose were analyzed with nonlinear FEM after the finite element model of the hose was established. It is found that the axial stress at the crown is the main factor affecting the strength of the hose. The results of the finite element calculation were consistent with the leakage position in the test, which shows that the finite element model is right. On this basis, through the parameterized modeling, the central composite experiment was designed, the parameter sensitivity analysis was performed, and the sensitive parameters affecting the maximal axial stress at the crown was acquired. The achievement can be used for optimization of structural parameters.
