| dc.description.abstract | This research paper present develops a material for improving the fatigue strength of the bogie frame of AARLT. The purpose of this research is to compare between the current material and selected material in order to protect the bogie frame from failure. In the analysis of the research ANSYS and FEMFAT software have been used to investigate the difference of these materials. The specimen S.N curve has been used to clearly differentiate the two materials. On the basis of the modal analysis the following results has been achieved. The equivalent stress of the current material is 2.0091e^8 and 2.0037e^7 for the selected material .the minimum safety factor of current is 0.4290 and 0.4302 for the selected one. The total deformation of the two material are 0.0013168 ,0.0013329 which lead to the researcher to say that the selecting material has less deformation than the current .FEMFAT software reveal that the selected material have greater endurance limit and survival probability ,which mean the new material will be more resistant. Based on that result, it is possible to conclude that the selected material is stronger than the current material .the bogie frame that is the most important part of the bogie will be safe and can withstand the overload. The study is significant and applicable because it introduce a knowledge on the material of the bogie frame in order keep it save by improving the fatigue strength .Therefore railway corporation should give attention on the phenomena. | en_US |
