Wear, Wheel, Train


The wear that occurs on the wheels of the Mass Rapid Transit Jakarta (MRTJ) train is abnormal wear at a higher depth level only at one point, causing new grooves. The MRT Jakarta train continues to operate with wheels that are experiencing grooved wear, because there has been no repair. This study aims to determine the causes and effects of grooved wear on the wheels. For this reason, in order to reveal the cause of wear, an analysis of surface morphology, chemical composition, physical properties, mechanical properties (hardness) and microstructure was carried out on 3 samples of brake blocks that experienced wear and one sample of brake blocks that had not been used as a comparison. From this study it was revealed that the composite material and cast iron in the rem blok construction complied with the manufacturer's specifications, however, the compressive strength of the composite material (29 MPa) was lower than the MRTJ requirement (35 MPa). The failure of the grooves on the train wheels is thought to be caused by the morphology of the brake block which contains cast iron on the surface which does not cover the entire surface of the brake block. The surface area of ​​the brake block that does not contain cast iron is in the same location as the grooved wear on the tread of the carriage. During high-temperature braking, the tread and the surface of the cast iron will soften, causing an increase in the wear rate of both components. During operation, increasing the compressive strength of the rem bloks can accelerate the formation of grooved wear on the tread. After knowing the cause so that the wheels do not experience grooved wear, it is necessary to modify the brake block both in terms of chemical composition and the morphology of the brake block surface.
