Studies of the electromechanical wear of contact pairs in the current collection devices of electric transports

摘要

In the article the results of experimental studies of electromechanical wear of contact pairs in the current collection devices of electric transports are presented. According to the analysis the corresponding mathematical models were drawn up for mechanical and electrical components of the wear process. The developed models allow one to take into account the impact on the wear process at the current collection operation parameters, i.e., humidity, dust content, and environmental temperature. The article presents a comparison of the experimental and modeling studies.
