Abstract

The Main objective of the study is to find out the basic running condition of KNR EMUs since the results can be useful in designing new EMUs. We had investigated the average annual mileages and decrepit levels. After that, we performed stress analysis for the carbody when uniformly distributed vortical loads due to the weight of the car body and passengers were applied to the underframes, in order to find out the most critical sections of the underframes and the effect of corrosion on the underframe strength.. Upon performing stress analysis, we carried out running tests of EMUs on the conventional line to measure dynamic stresses applied to the underframes.
