| Abstract: | The strength evaluation method of the airborne computer is well worth studying because of its peculiar composition and complex working condition. A new evaluation method adopting static strength, stiffness, fatigue, shock as well as classical strength theory is put forward. An airborne computer was evaluated successfully by finite element analysis software with this method which establishes foundation for the reliability evaluation of the airborne computer. |
