摘　　要：机载计算机组成特殊、工作环境复杂,其强度评价方法是很值得探讨的问题。结合经典强度理论,提出了采用静强度、刚度、疲劳寿命和冲击相结合的强度评价方法。采用有限元分析软件,运用该方法对某机载计算机进行了强度评价,取得了预期的效果,为机载计算机的可靠性评价奠定了基础。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.
