摘要

PROBLEM TO BE SOLVED: To provide a method for designing a high strength bolt friction joint capable of realizing a rational number of high strength bolts and arrangement of high strength bolts and provide a high strength bolt friction joint designed on the basis of the method.SOLUTION: This invention relates to a high strength bolt frictional joint subjected to a frictional surface treatment where a coefficient of friction is dependent on a contact pressure, and it satisfies a relation of μ=14×10×t+4×10×(l+w-1.35×2×r)+0.24, where l(mm) is a frictional surface length per one high strength bolt in a stress applying direction, w(mm) is a frictional surface length per one high strength bolt in a stress crossing direction, t(mm) is a doubling plate thickness, and μ is a sliding coefficient when relations of l≤1.35×2×rand w≤1.35×2×rare applied. Since a target sliding coefficient μ and ts are set in advance and land wcan be set to cause this sliding coefficient μ and ts to be satisfied, it is possible to attain a high strength bolt frictional joint where a rational high strength bolt can be arranged.SELECTED DRAWING: Figure 1
