Abstract

Automotive chassis is very important part of carrying the entire load of all essential components like engine, propeller shaft, differential, gear box, braking system, suspension, etc. Moreover chassis should be high stiffness and high strong enough to withstand high amounts of twisting and bending loads which are subjected on it. In this paper, stringer component is fabricated and tested experimentally in the universal testing machine (UTM) testing machine. Stringer component should resist the maximum load and it must exhibit high strength and high stiffness. The method followed to achieve the high strength stringer is an experimental failure analysis of the structure while the structure is subjected to 3- point bending in a universal testing machine. The two different stringer structures are selected for experimental failure analysis under 3- point bending action and the component is taken from the Tata 2516 TC truck chassis. The stringer component is taken in two forms. They are C-stringer, and Hat stringer. The testing is carried out in bending by applying the load on centre to the stringer. The breaking loads, the deformation of the stringer at breaking load, ultimate stress are calculated on the UTM testing machine. After that, the graph between stress-strain, stress-deformation, and load-deformation is obtained from testing. From the results, the strength of the hat stringer is more than the strength of the C-stringer.
