고력볼트용 풀림방지너트를 적용한 고력볼트 마찰접합부 특성

The use of Saper-lock nut increases that the high strength bolt joint doesn't may be generated to be solved by the repetitive impact or load action of the bolt. However, when using the Saper-lock nut, the investigation of the internal force change of the high strength bolt joint is the incomplete actual condition. This research decides on the temperature, clamping force, and hole size for the variable to the high strength bolt friction joint applying the Saper-lock nut and confirms the effect of the behavior through the experiment. It tries to grasp the connecting characteristic and change when using the Saper-lock nut in the high strength bolt joint
