| Abstract: | Contact resistance is an important factor to judge the reliability of current-collecting quality of pantograph-catenary.And it is expected to get smaller and stable contact resistance in the process of locomotive run.Based on micro resistance characteristics of pantograph-catenary e-lectrical contact interface,the effect of contact area and contact number of spots on the quality of pantograph-catenary current-collecting are analyzed in detail,and a statistical model of surface characteristics is established to quantify the electrical contact interface resistance.The test results show that the analytical method is feasible and effective. |
