Type: conference-paper
Abstract: Railway axle and railway bearing are critical railway components. It is needed a method to analyse them. In this work, static and dynamic analysis are presented. Static analysis is presented by analyzing the design of railway axle through finite element analysis (FEA). Dynamic analysis is presented by analysing the outer race fault of the railway axle bearing based on vibration analyses. Initially, a laboratory-scale of wheel-set test-rig was designed using 3D computer design, then, the design was analysed the shear stress and deformation by FEA. Based on this design, the laboratory wheel-set test-rig was manufactured for conducting dynamic experimental tests. The vibration responses obtained in the tests were then analysed using fast Fourier transform (FFT) and Hilbert-Huang transforms (HHT). The results show that the stress and the deformation are small enough. Therefore, the design can be applied. In the vibration analysis, EMD process provided good results for analysing signals.
