Methods for predicting the wear of contact inserts of electric rolling stock pantographs

The use of current-collecting contact elements with an extended service life is one the most economical and least costly ways to ensure reliable, environmentally friendly power transmission rolling stock. To assess predict life, Omsk State Transport University developed successfully tested a methodology for conducting experimental studies inserts pantographs, including bench tests each pair materials. obtained test results are initial data predicting wear pairs assessing their in real operating conditions. Prediction carried out using mathematical modeling processes, taking into account maximum possible number factors that negatively affect elements. purpose this article improve method wear, high speeds. model forecasting makes it reduce time labor costs by 2.5 - 3 times resource element pair.
