A34 ボルト結合体のFEM解析精度を低下させない結合部の単純化モデルの注案(OS1 最新工作機械(3))

Abstract

The bolted joint has been frequently used as a jointing method of structures, because it is easy to joint structural elements. In order to accurately grasp the static characteristic of these structures, the analysis considering the bolted joint is required. However, if FEM analysis of static characteristics of the bolted joint with high accuracy is necessary to cany out, the number of elements in the model for analysis increases dramatically. In this study, we propose the simplified model for analysis of the bolted j oint, which does not degrade the accuracy of analysis. As a result, we could the simplified model for the bolted joint.
