摘　　要：本文提出了一种可模拟飞行器翼面等溥壁结构的强刚度可靠性分析方法。给出了在Mises屈服条件下平面应力元件强、刚度安全裕量方程。讨论了强度失效模式和刚度失效模式的相关性。In this paper,a method of strength and stiffness reliability analysis for bar plate structural systems,which can simulate the wing of the flyers,is presented.Based on the Mises's yield condition,the element safety margins about strength and stiffness of the plane stress element is derived.The correlation of failure modes between the strength and stiffness is discussed.
