螺栓联接的可靠性设计

Reliability Design of the Bolts Connection

运用可靠性理论 ,以受轴向载荷紧螺栓的强度计算为例 ,阐述了螺栓联接强度的可靠性设计的常用方法及当量可靠度的概念 ,并将新的设计结果与传统的设计计算相比较 ,说明可靠性设计更合理、更符合客观实际。

The strength calculation of an axially loaded bolts connection,using the principle of reliability design,is taken as an example to expound the methods most in use of the reliability design of the bolts connection strength and the conception of the equivalent reliability.In comparison with traditional design methods,the method proposed in the paper is more reasonable and tallied with the actual situation.
