전단볼트의 동적파단특성

초록

Shear bolt is used to prevent deployment of the crash energy absorber at impact force lower than prescribed force. If the impact force reaches the prescribed force, the shear bolt is fractured and the crash energy absorber deploys. In this paper, experimental results on fracture characteristic of the shear bolt subject to impact speed and gap which is defined as a distance between lower and upper surface in the shear fracture area, were studied. In order to study the effect of the impact speed quasi-static (v
