The influence of vertical load transients on wheel and rail deterioration
The influence of high magnitude transient loads on deterioration of wheels and rails is studied. Initially the frequency of occurence of transient loads needed to influence rolling contact fatigue crack growth in wheels is established. The focus is then turned to the influence of fatigue crack initiation and growth in rails. Alert limits are proposed and discussed along with the need for further studies.
