A theoretical analysis is made on the impact of contact lines wear on reliability of current collecting and security of catenary. And a two-dimensional vertical coupling vibration model of pantograph/catenary is established by Ansys. An analysis is made on pantograph/catenary interaction when contact lines wear for 0, 10, 15, and 20 %. The result shows that with increasing wear of contact lines, contact force changes violently and the dynamic displacement and stress increase, which has a severe effect on current-collecting reliability of pantograph and security of catenary. And the locomotive cannot run normally and safely when contact wires wear over 15 %, so it needs to take some measures.
