Further, stress concentration near the fastening portion can be significantly moderated by arranging a stress-moderating layer in which the coefficient of elasticity is suppressed to about 1/3 that of resin for coil molding on the outermost layer.
However, the bolt fastening method(a promising way for fastening ground coils) has the problem of possible damage resulting from compressive creep andstress concentration near fastening portions due to fastening axial force in the resin portion..
The RTRI performed comparative verification using a method tosimulate steps on fastening surfaces using afasteningportion model to forcibly perform bolt fastening, and confirmed that stress generated near the fastening portion can be reduced to about 1/3 of the value found with conventional metal bushing, and to the order of about 1/2 compared to cases when improved metal bushing was used Fig.
Major Results of Research and Development in Fiscal 2008 V-1 Fastening devices between ground coils and guideways used in outdoor environments for long periods of time under conditions of vibration by electromagnetic forces during the running of linear-motor railway vehicles are important components that affect maintenance management costs and system reliability.
