Abstract

This paper is concerned with the formulation of an approximate analytical model describing the total wear on both high and low rails as a function of the angle of attack ψ. The rail life γ(ψ) is obtained in this model as follows as: γ(ψ) = l(ψ-m)2+ nψ≤ 0.0058 radγ(ψ)=Pψ+q ψ ≥ 0.0058 rad where l,m, n, p and q are constants which can be determined for a specific set of boundary conditions. The results of applying this equation to various values of ψ are compared with field data and good agreement is observed. © 1984.
