内燃机缸盖螺栓组联接的模糊可靠性设计

The Fuzzy Reliability Design about the Bolt-joint Set of Engine Bonnet

将模糊数学理论引入可靠性设计中 ,考虑预紧力和轴向变载荷状态的影响因素 ,建立螺栓联接的模糊可靠性设计准则 。

Based on the fuzzy mathematics, it establishes th e rules of the fuzzy reliability design for the bolt-joint set, discusses the e ffect of pre-tighten force and the axial changing load on the set, and shows an example.
