Abstract
Background
A strong electromagnetic force is the major cause of vibration in dipole power supply cables. Moreover, the long-term operation of cables under vibration conditions leads to structural fatigue failure.
Purpose and methods
To investigate the cable-laying scheme of a dipole power supply, a finite element model for the electromagnetic–structural coupling between cables and cleats was established. The electrodynamic forces were simulated for fixed-length cables in the horizontal, vertical, and bent models under pulse-current excitation. Subsequently, based on the optimized arrangement mode, the deformation of the cables and the stresses of the cleats were obtained.
Results
A small cable electrodynamic force was observed in the positive–negative interlace arrangement, and the cable deformation was caused by electrodynamic forces. The maximum cleat deformation occurred at the position with the largest electrodynamic force, where the cleats were reinforced. Moreover, the mechanical characteristics of the cables and cleats under pulse-current excitation are described intuitively and quantitatively, providing theoretical support for the cable-laying scheme of the dipole power supply.
