Abstract: There is a close relationship between the wear loss and the pressure between the pantograph slide and the contact wire. Finding the optimal load of the lowest wear of slider makes economic sense. Aiming at the inconvenience of mechanism modeling, Support Vector Machine（SVM） is used to establish the regress model with the dependent variable of wear loss and pressure, velocity and current as the independent variable. The optimal load on the condition of the fixed velocity and current are acquired utilizing the simplex method. A numerical example gives the reference for the further applications of the SVM model.

Key words: wear loss, Support Vector Machine（SVM）, optimal load
