Methodology development for estimating the residual resource of diesel locomotive traction generator brushes

Abstract

The article presents the formation of a mathematical model of the wear process and estimation of the residual resource of synchronous traction generator brushes. The authors propose to consider the peculiarities of operation and technical condition of the brush assembly in calculating the residual resource of electric brushes. The data arrays collected by the on-board monitoring system are analysed and required parameters for determining the residual resource of electric brushes are identified. The article provides a mathematical model of wear intensity of the traction generator electric brushes. The authors present the experimental research plan for determining the mathematical model coefficients. There is a scheme of experimental installation for determining the residual resource of synchronous generator brushes. The authors obtain dependences of the residual resource value on the change of operating modes.
