| Abstract(J) | 車体のマルチマテリアル化における主要な接合方法の一つであるねじ締結は外力を軸部で支えるために高い接合強度を有するが，動的な剛性は締付力と部材の表面性状によって変化する．本稿ではねじ締結部の剛性変化を再現する有限要素シミュレーションの基礎理論，検証実験，モデル簡略化への取り組みについて述べる． Translation |
| Abstract(E) | Mechanical fastening such as bolted joints is one of major joining methods for multi-materialization of automobile body. Bolted joints enable to join metallic materials and nonmetallic materials with high joint strength because external load is supported by bolt axes. On the other hand, stiffness of bolted joints easily changes depending on clamping force and surface texture at contact surfaces of jointed members. This article briefly introduces the basic theory of the interfacial element for FEM which simulates the stiffness changing of bolted joints. In addition, it describes results of verification experiments and trials of model simplification for large-scale simulations. |
