Stress analysis of different cross-section for passenger truck chassis with a material of ASTM A148 Gr 80–50

Abstract

This research aims to optimize on an optimal condition to increase the capacity of passenger truck chassis and focus analysis of stress for the different cross-section in different loading conditions with the consideration of stress concentration factor. Chassis is a significant component in the vehicle, and different types of failures occur due to static loading conditions. Unbalanced loading conditions in the construction of lorry and passenger trucks; the actual unloading carrying capacity for passenger bus is less than the lorry one in the local area. Maximum stress and maximum deflection are the main criteria for designing the passenger truck chassis. The present study determined the maximum stress and maximum deflection to recognize critical regions under loading. Stress was analyzed using different cross-sections under different loading conditions. As a result, I cross-section is important to increase the chassis capacity, and the effects of stress concentration factor are necessary to choose the essential profile. And that used to fix chassis characteristics of the static condition. Finite element analysis enables to predict the region that tends to fail due to loading implemented. This study definitively answers the question regarding chassis stress analysis in different cross-sections and loading conditions. I cross-section is the best, which has less stress and deflection.
