Abstract Electrified railway catenaries are responsible for the stable transmission of electricity to locomotives. Normally, stitched wires are used to lower the unevenness of elasticity of catenary, which is able to improve current collection quality. But the selection of the stitched wire parameters is very difficult in practical engineering. To deal with this problem, the catenary of Chengdu-Chongqing high-speed railway is selected as analysis object. The nonlinear spatial beam element is used to construct the model of catenary. The stitched wire tension, length of stitched wire and the position of dropper are selected as variables to analyse the effect of stitched wire parameters on the current collection quality. The result shows that the stitched wire has considerable effect on the current collection quality, which can be revealed by observing the elasticity of catenary. The optimization strategy of stitched catenary for Chengdu-Chongqing high-speed railway is suggested.
