Investigation of material impact on Truck frame design through Structural Analysis

The truck chassis core purpose is to support the payload due to the various components located on it. The chassis was encountered to dynamic vibration due to the road irregularity and excitation of vibrating mechanisms, when the vehicle is moving on the road. Chassis helps to keep the automobile rigid and stiff. This paper investigates the material impact on the truck frame design. Two different materials were analysed on the heavy truck frame through finite element analysis. The Al alloy and Structural steel materials were applied on for channel cross-section of the truck frame. The results were compared and the best truck chassis material was identified with lower stress and deflection.
