Abstract
Train is one of the modes of transportation that has unique characteristics and advantages because of its ability to transport passengers and goods in bulk, efficiently, sparingly in the use of space, and safe. The comfort and safety of the train cannot be separated from the structure of the train and the existing rail structure. A railway system generally consists of train structures (carriages) and railroads. The rail structure consists of the rail itself under which there are railway sleepers and a foundation or ballast. The sleeper serves as the foundation on which the rail rests. The materials or materials used for sleepers are of various kinds, such as wood, steel, or reinforced concrete. Due to receiving the load from the train tracks, the sleeper used prestressed rebar concrete or reinforced concrete with tension steel, which is useful so that the load from the train wheels can be neutralized so that the sleepers can withstand impact loads. This study aims to analyze the effect of impact loads and variations of railway sleeper reinforcement on the resistance of railway sleepers. Finite Element Method (FEM) modeling was used to simulate the stress on the sleeper structure. The variety of reinforcement used is 4, 6, and 8 rods with 7 different formations. The results obtained are in the form of stress, load, and displacement values. The value of the stress on the whole system is 1860 MPa. The maximum load value is 245,33 kN for variations of 6 reinforcements formations 1. Displacement value is 14,03 mm. The simulation results and graphs show that the correct arrangement and amount of reinforcements increase the resistance of the railway sleeper.
