Effect of the strip inclination angle on the friction and wear behavior of contact strip against contact wire with electric current

摘要

A series of tests were conducted to study the effect of the strip inclination angle on the friction and wear behavior of a contact strip rubbing against a contact wire with electric current using a ring-block-type test machine. The arc voltage and electric current were measured throughout the tests to evaluate the scaled accumulated arc energy. The variations of the wear rate of the carbon strip and the scaled accumulated arc energy with strip inclination angle were obtained. Experimental results show that the strip inclination angle has an effect on the friction and wear behavior of contact strip against contact wire with electric current, and an appropriate strip inclination angle can decrease wear of the contact strip.
