Abstract

Aiming at the fracture failures of a launcher frame in the vibration test, the failure cause analysis and structural improvement were carried out. The finite element software Abaqus and the fatigue life analysis software Fe-safe are used for joint simulation to obtain the stress distribution and fatigue life of the launcher frame under the vibration load. The simulation results show several obvious stress concentration phenomenons at the fracture position of the structure, and the fatigue fracture position is consistent with the vibration test. After structural improvement, the fatigue life of the launcher has been increased by 18.6 times, and the overall fatigue life meets the expected usage requirements.
