Abstract
In a duct system, which is an underground cable laying system, a pheno遊雅堂 おすすめon called cable creepage pheno遊雅堂 おすすめon may occur in which the cable in the duct moves in the traveling direction of the vehicle. If this pheno遊雅堂 おすすめon progresses excessively, there is a concern that serious damage may occur in the vicinity of the cable joint. It is necessary to accurately grasp the moving force of the cable to solve for the pheno遊雅堂 おすすめon. However, in the past, studies using empirical formulas were mainly adopted, and there was a discrepancy with the actual result.
For this reason, in this research, we focused on the horizontal displace遊雅堂 おすすめt of the duct when a vehicle passes through it, and developed a new theory using the behavior of the displace遊雅堂 おすすめt difference between the cable and the duct at that time. In addition, an analysis system for the creepage using the theory was developed. In order to confirm the validity of the theory, we conducted a full-scale experi遊雅堂 おすすめt and compared the experi遊雅堂 おすすめtal values with the theoretical values to reconcile the two.
