Selection of Pantograph Strip/Contact Wire Couples in Catenary/Pantograph System
A serials of experiments were carried on the pin-on-disc friction and wear tester. The friction and wear behaviors of on four materials couple with electric current were studied on in different conditions. The result indicates that properties of materials couple have a significant influence on the test results. The friction coefficient is the highest in process of the copper-impregnated metallized carbon rubbing against pure copper couple, and its wear volume of carbon strip material is also the largest. However, the friction and wear volume of copper-impregnated metallized carbon/stainless steel and pure carbon/pure copper couples are lower. Therefore, both friction couples are appropriate for pantograph strip/contact wire couple.
