Abstract

Construction of the truck floor bed is usually made up of prismatic beams. Currently in this article concept of the beams of uniform strength is used to avoid the concentration of high stress at critical points. The strength of beam mainly depends on cross section and the bending moment along the span. Highest stress value found in the critical sections mostly in the supports and in all other sections, the stress is well below the permissible limit, which means that the material potential capacity to carry load is not fully utilized. Hence, ‘I’ section is used for obtaining higher moment of inertia and also in order to enhance the load carrying capacity the variable cross section beams is used to resist the corresponding bending moment. The floor bed with payload capacity of 20 tonnes is used in the current study and also it is subjected to off design impact load using finite element method. The usage of beams of uniform strength have given better results and also optimised the total weight giving the same load carrying capacity. Any additional weight in truck reduces the efficiency and increases fuel consumption which leads to carbon footprint and adaptation of this technique in present work proved to be cost effective upon implementing in mass production.
