| Abstract: |
| Objective To explore the fracture mechanism of aviatic optical devices and study the accelerated life Test.Methods Theoretical studies were performed using optical devices for aviation rupture mechanism of injury; the causes of different mechanisms, performance and preventive measures were analyzed. Results The atmospheric friction and solar radiation factors on the optical surface air temperature was analyzed, and the aviation optics lifetime was calculated by accelerated life test method based on the Arrhenius model theory.Conclusion Brittle fracture injury rupture failure and fatigue failure is the main risk factors of aviation optics fracture. |
