Hailemariam Fisseha Nega [2] | Yang Hui [2]
Abstract: Now day-s Vehicle trucks plays a more important role in all economy activity of transportation. The major focus in the truck manufacturing industries is design of truck chassis with more pay load capacity and possible less weight. And a number of analytical and experimental techniques are available for the analysis of the automobile frames. An important aspect of chassis- design and analysis is the stress distribution and fatigue life of prediction process. The stress analysis is important in fatigue study and life prediction of components to determine the critical point which has the highest stress. In order to achieve a reduction in the magnitude of stress at critical point of the chassis frame, side member thickness, cross member thickness and position of cross member from rear end were varied. Also, in order to avoid matching the natural frequency of the chassis with the excitation frequency, natural frequencies and vibration modes have been analyzed during the loading conditions. Fatigue is one of the most important parameters to consider when designing truck components. Thecomponents are typically subjected to dynamic loads when in service. In this paper, an effort is made to review the investigations that have been made on the different fatigue analysis techniques of vehicle truck frames. A number of analytical and experimental techniques are available for the analysis of the automobile frames.
