| Abstract(J) | 本論文では，ユンカー緩み試験における緩み過程を，ナット締付力の繰返数による変化として捉え，これを3次元FEM解析により求める．その結果をユンカー緩み試験で得られた結果と比較して，ピッチ差付きナットの耐緩み性能を評価し，そのメカニズムにも言及する． Translation |
| Abstract(E) | In our previous studies, a bolt-nut connection with slight pitch difference was considered towards realizing anti-loosening performance and high fatigue strength through axisymmetric finite element method (FEM) and experiment. Also by applying three-dimensional FEM, the nut tightening/untightening process was analyzed to confirm anti-loosening performance indirectly. In this study, Junker's type loosening experiment based on DIN standard is used to confirm the anti-loosening performance directly. The results suggest that suitable pitch difference may provide good anti-loosening performance. The 3D FEM simulation is in good agreement with the experiment. The anti-loosening of the pitch difference nut is discussed by comparing the loosening of the normal nut. |
