Shape Optimization of AALRT Wheel Profile

Atalay Tesfaye
After optimization and performance analysis the result of this paper shows optimized wheel profile has wear index of 1900N, 420N and 56N on R50curve, R150 curve and on straight track respectively.  ...  Therefore wheel profile optimization has great impact on wheel Rail wear and AALRT have to work on it for better result.  ...  NJ Transit reported "higher wheel wear on the center trucks of its LFLRV fleet than on the wheels of the motor trucks" and "very high rail wear on sharp curves."  ...
