A quantitative model to estimate rail surface failure
Date of Original Version
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.
