太径の高力ボルトを用いた摩擦接合継手の接触圧を考慮したすべり係数に関する解析的検討

抄録

In this study, we consider using large-diameter bolts for the standard thickness joints used in railway structures and making the minimum center spacing of the bolts smaller than the current standard. Then, we study for the purpose of shortening the length of the splicing plate and making it lighter. As a basic study, the relationship between the contact pressure and slip coefficient between the mother plate and the splicing plate when the tightening plate thickness was changed was confirmed analytically. In addition, we also verified the arrangement in which the minimum center interval of bolts is narrower than the current standard.
