Trains are
a very important mode of transportation for freight and passengers in
Indonesia. This encourages PT KAI, which is a train operator in Indonesia, to
improve its performance. Currently PT KAI uses several types of locomotives.
CC201 locomotives made in 1977-1978 and CC203 made in 1995 are locomotives that
are still widely operated. Fuel consumption is one of the components of train
operating costs, the percentage of which reaches more than 30%. Railroad fuel
consumption is strongly influenced by various factors, one of which is the
aerodynamic performance of the locomotive.
This study presents an evaluation of the aerodynamic performance of
CC201 and CC203 locomotives. The research stages include direct measurement of
locomotive geometry and dimensions, CAD drawing creation using SoildWorks and
aerodynamic evaluation using ANSYS software. The simulation results show that
the flat front design of the CC201 locomotive has greater aerodynamic
resistance. This can be seen from the pressure contours and turbulence around
the locomotive body. This causes the drag force of the CC201 locomotive to be
44% greater than that of the CC203 locomotive.
