Abstract :
The wire rope experienced an unexpected failure at the Kariangau container port, this could cause work accidents and also disrupt the activities of the Kariangau container port, therefore it is necessary to carry out a failure analysis. Research on failure of wire rope type 6x36 IWRC on Rubber Tire Gantry ZPMC has been carried out. This study aims to analyze the mechanism of failure of wire rope type 6x36 IWRC on Rubber Tire Gantry ZPMC and analyze the structure modeling of wire rope type 6x36 IWRC on Rubber Tire Gantry ZPMC with the finite element method. The methods used are SEM-EDS testing, optical microscope testing, metallographic testing, simulation using ANSYS 17.2 software. The results of the EDS SEM test show that there are many cracks on the surface far from the fault, the beachmarks fault pattern is a fatigue failure. The results of the optical microscope test showed that there was a concentration of stress on the inside of the wire rope. The results of metallography showed that the microstructure of ferrite and pearlite were evenly distributed and did not change the microstructure. Static simulation 15 tons results obtained for Equivalent von misses maximum stress of 475 MPa on the inner side of the wire rope is still below the yield strength of the material and fatigue simulation is obtained for a constant load of 15 tons which is 13997 cycles compared to failure data of 1,5 years with 18000 cycles. Further investigation using miner rules stated that if the D value of 1,2 is greater than 1, the wire rope will be damaged due to fatigue failure.
