Stress and Strain Analysis of Combustion Pressure Test for Thin-wall Cylindrical Parts
The combustion chamber belongs to the thin-wall cylinder parts,under the centralized load will produce complex elastic-plastic deformation.The combustion chamber adopts the radial end surface sealing form for the hydrostatic test,and the complex elastic-plastic deformation is caused by the radial,axial and circumfer-ential concentrated load in the clamping process.The finite element method is used to analyze the deformation process of the combustion chamber under the action of concentrated load,determine the reasonable surplus of the radial end surface sealing,and guide the actual production according to the simulation results,thus getting good results,the selected seal,the pressure pressure have certain guidance and reference significance of the pressure.
