Abstract

The jig production process at PT IMS focuses on strength, function and production speed. The known problem is the higher strength and cost of producing jigs because the production process is not much at the trial and error stageThis study analyzes the static strength of the jig side frame bogie of the Jabodebek LRT with the parameters of the safety factor and deformation values.Static loading simulation method testing process used is conducted by using Finite Element Method software. It is counted manually to one of conditions to obtain the voltage value compared to the simulation results. This analysis is in form of measured jig design with safety factor and deformation value. The redesigning aim is weight decreasing efficiency. The simulation obtained result in jig early design is the safety factor value 25 and deformation value 0,045 mm. After jig dimension decreasing has been conducted, the redesigning result for safety factor value is 32 and the maximum deformation is 0,114 mm. The results of both simulations are considered as safe because the safety factor values are more than 2 and the deformation value are less than 0,5 mm. Redesigning by decreasing dimension gives better safety factor yet the deformation value increases.

Abstract

Bogie frame adalah bagian utama bogie yang digunakan untuk menopang seluruh badan kereta api, menghubungkan bogie ke wheel set, dan menopang komponen bogie lainnya. Beban terbesar kereta api diterima bogie frame sehingga diperlukan analisis kekuatan struktur. Penelitian ini fokus pada analisis kekuatan desain struktur bogie frame kereta ukur jalur LRT Jabodebek pada kondisi exceptional loads. Tujuan penelitian menganalisis nilai tegangan objek penelitian akibat exceptional loads dan memastikan hasil simulasi memenuhi kriteria keberterimaan standar EN 13749. Hasil penelitian adalah nilai tegangan maksimum, nilai defleksi maksimum, dan lokasi tegangan maksimum tiap load case. Nilai tegangan maksimum hasil simulasi dibandingkan dengan nilai yield strength material sebesar 355  MPa. Dari dua belas load case exceptional dihasilkan nilai tegangan maksimum kurang dari nilai yield strength material. Nilai tegangan maksimum tertinggi terletak pada stopper transversal bracket yaitu sebesar 258 MPa dan defleksi maksimum terjadi ketika kondisi derailment (anjlok) yaitu sebesar 12,1 mm. Bogie frame kereta ukur jalur LRT Jabodebek memenuhi kriteria keberterimaan standar EN 13749 ketika kondisi exceptional loads. Bogie frame is the main part of the bogie used to support the entire body of the train, connect the bogie to the wheel set, and support other bogie components. The biggest load of the train is received by the bogie frame, so an analysis of the strength of the structure is needed. This study focuses on analyzing the strength of the bogie frame structure design for the Jabodebek LRT track under exceptional loads conditions. The purpose of this research is to analyze the stress value of the research object due to exceptional loads and to ensure that the simulation results meet the acceptance criteria of the EN 13749 standard. The results of this study are the maximum stress value, maximum deflection value, and the location of the maximum stress in each load case. The maximum stress value of the simulation results is compared with the material yield strength value of 355 MPa. Of the twelve exceptional load cases, the maximum stress value is less than the yield strength of the material. The highest maximum stress value is located at the stopper transverse bracket, which is 258 MPa and the maximum deflection occurs when the derailment condition is 12.1 mm. The bogie frame of the Jabodebek LRT track measuring train the acceptance criteria of standard EN 13749 when conditions are exceptional loads.
