Abstract

The title of this project is ‘Investigation on Corrugation Effects and Growth in High Speed Railway by Using CAE Software’. Vibration and noise is the effect of corrugation on the railway surface. This abnormalities defect will produce the uncomfortable noise to passenger in the train. The bigger of wavelength of corrugation, the louder noise will produce by railway. This study will be more focus on the corrugation growth rate on the high speed railway. The corrugation growth will be study by create the simulation of whellset passage by using CAD and CAE software suite HyperWorks (HyperMesh, MotionView, HyperView) and compare the result of experiment with the previous study. The simulation will be based on the parameters of study “Simulation of the evolution of rail corrugation using a rotating flexible wheelset model” of the previous study. The improvement of the simulation result compare to the previous result will be the result of this project. Finally, the test rig prototype will be design for actual experiment in further improvement. By having the test rig, the result of the simulation can be compare with the actual result for perfect and accurate result.
