Fracture Failure Analysis and Improvement of the Thrust Chamber Heat Insulation Frame
To deal with the fracture of heat insulation frame of the thrust chamber used in attitude control power system during mechanical environment tests,fracture analysis and strength analysis of the failed component were carried out.The results showed that there was severe stress concentration at the root of the supporting rib of the heat insulation frame under high-order random vibration condi-tions,leading to fatigue fracture.By improving the supporting rib structure of the heat insulation frame,and verifying through strength analysis and thrust chamber mechanical environment tests,the heat insulation frame failure did not occurred again,indicating that the improvement is reliable and effective.
