Abstract

A common form of cantilever used to support the overhead line equipment is assembled from steel tubes with crimped in end fittings. Within the older UK stock, these end fittings have been seen to come loose. In this paper, the crimping operation and the pull-out strength of the joint created is determined using finite element analysis (FEA). This analysis demonstrates the reduction in joint strength when sleeve is used to allow a small fitting to be used in a larger diameter tube. A new, machined from solid fitting is proposed and tested. Good correlation between the practical tests and the FEA is observed.
