“…Investigations have been and are being carried out ( [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]) concerning the wear behaviour during strip and wire interaction and the development of materials for both strip and wire in order to enable the current collection keeping acceptable wear rate of the two contacting elements.…”

Main contributions to the wear in the sliding contact between pantograph's strip and catenary's wire can be classified as: i) mechanical contribution, due to friction, ii) electrical contribution, due to current flow at the contact and iii) electrical arcs contribution related to power dissipated during arc generation. In this work, a heuristic wear model for the contact wire, which accounts for the mentioned three main contributions to the wear, is presented. After a tuning phase with results obtained by an experimental campaign aimed at evaluating the wear for the couple "pure copper contact wire -Kasperovski contact strip", the wear model is used in combination with a dynamical electromechanical model able to reproduce the electromechanical pantograph-catenary interaction.Suggested Reviewers: Takayuki Usuda Railway Technical Research Institute usuda@rtri.or.jp Dr Usuda is senior researcher on the interaction between pantograph and catenary and on related problems.Rafael Manory M&H Materials Pty Ltd rmanory@kuee.kyoto-u.ac.jp Dr Manory studies problems related to the interaction between pantograph and catenary, to the sliding wear, to the electromechanical contacts and to the wear tests for copper and graphite materials.Guangxiong Chen Southwest Jiaotong University, State Key Laboratory of Traction Power, Chengdu, China chen_guangx@163.com Author of different works on electromechanical problems related to pantograph-catenary interaction.Dear Tribology International Editors, we would like to submit the present paper titled " Electromechanical interaction between carbon based pantograph strip and copper contact wire: a heuristic wear model" for a possible publication on your review.The paper deals with a heuristic wear model, tuned using results obtained by a laboratory campaign on the couple "pure copper contact wire -Kasperovski contact strip", which is used in combination with a dynamical electromechanical model able to reproduce the electromechanical pantographcatenary interaction. This procedure try to reproduce the real conditions that cause the wire's wear evolution.The practical application of the presented procedure can be useful to estimate the maintenance costs related to the wear of contact wire and to assess the effective benefit of proposed innovative solutions for pantographs and catenaries.Best Regards, Giuseppe Bucca, Andrea Collina giuseppe.bucca@polimi.it Cover Letter I confirm that this paper is original and it has not been published previously and it is not under consideration elsewhere.Giuseppe Bucca, on behalf of all authors *Statement of OriginalityMain contributions to the wear in the sliding contact between pantograph's strip and catenary's wire can be classified as: i) mechanical contribution, due to friction, ii) electrical contribution, due to current flow at the contact and iii) electrical arcs contribution related to power dissipated during arc generation.

“…Higher electric current is need to support the train to faster run. However, high electric current flowing from the contact wire to the contact strip can produce a large amount of heat, which leads to the serious wear of the contact materials in the process of the high-speed sliding with electric current [1][2][3][4][5]. The widely technical investigation and laboratory experimental tests on the wear of the contact materials with electric current have been carried out in recent years .…”

“…It was proved that higher sliding speed and electric current would cause more serious wear of the contact materials [10,13]. Some scholars [5,[17][18][19][20] think that arc discharge is a main reason of severe wear of contact materials in the process of the sliding wear with electric current. However, all above researches have been carried out at low sliding speeds below 150 km/h.…”

“…Two main challenges of these applications are to minimize both arc discharge (which occurs when contact is lost between the two conductors, due to the mechanical separation) and thermal wear [1,2]. In the past decades, pure metal, pure carbon, powder metallurgy composites and metalimpregnated carbon have been successively studied to address these challenges [3][4][5][6][7][8][9][10]. However, there are still many disadvantages for those materials in practical applications.…”

“…Pure metals are prone to arc discharge, which generates high friction with contact wires, causing heavy wear of both the contact strips and the wires [10]. Pure carbon exhibits high electrical resistivity and low mechanical strength [4]. Powder metallurgy composites (such as copper-graphite composites [7]) usually undergo heave wear, and are relatively expensive.…”
