Abstract
Modern rolling stock must have high reliability, as it provides high-speed movement of goods andpassengers. This applies to all its constituent parts, components and assemblies, particularly those thatprovide traffic and security are the foundation of the locomotive as a whole. Since from here it is necessaryto assess the reliability of mathematical responsible units of electric rolling stock and, in particular, currentcollectors.The stability of the current collection at railway roads depends on many factors, including thecharacteristics of the pantograph and contact network. Interaction pantograph suspension and contact is acomplex process, especially at high speeds. To ensure continuous quality current collection and Currentcontact network must have high reliability.In case of refusal trolley stops rolling stock supply electricity. This can lead to temporary, economicor material costs. To avoid this, specify resource pantograph and yohoskladovyh.
