Abstract

The paper provides a method for diagnosing current collectors of freight electric locomotives in the Republic of Uzbekistan in order to increase the reliability of current collectors, as well as reduce the time for their operation. A large number of failures attributable to current collectors, in particular to current collector inserts, were revealed. Improving the reliability, which will improve the reliability of the electric locomotive as a whole. To date, the electric locomotives of the park of the Republic of Uzbekistan do not have the diagnostic tools to determine the condition of current collector inserts. The article provides an algorithm for determining the state of slip rings, as well as its functional diagram. The method for determining the state of collector inserts is based on vibrational movements of the collector insert. During operation of the current collector, wear of the collector insert occurs, which leads to a decrease in the mass of the collector insert. When the mass changes, the vibrational acceleration of the collector insert changes. The change in vibrational acceleration is estimated using an accelerometer. The reliability of scientific statements and results is justified theoretically and confirmed by experimental studies
