Analysis of Dynamic Loading on Automatic People Mover System (APMS) Bogie Frame According to UIC Standard

Abstract

The purpose of this research is to conduct numerical analysis and verification of APMS bogie frame to withstand maximum dynamic loading with finite element analysis and to conduct design modification if bogie is not achieving safety criterion and infinite life cycle. Stages of this research was collecting data and APMS bogie drawing from PT. INKA Madiun, then conduct identification of bogie model structure, which included quality validation of Solid CAD model and mesh quality valiadation, then determination of boundary conditions for dynamic loading to acquire simulation of fatigue loading analysis or fatigue of material due to dynamic loading. From 3rd load step smilation showed that alternating stress result was 75.813 MPa which is under the limit of High Cycle Fatigue, 97,36 Mpa, and safety factor 1.25 so that until this stage was still safe. Limit of material SM 490A touhgness used for bogie frame manufacturing on cycle 106 or High Cycle Fatigue (HCF) was 97.36 MPa.
