A vehicle frame, also known as its chassis forms the backbone to all vehicles. It is one of the important parts that used in automobile industry. It is a rigid structure which acts a skeleton to hold all the major parts together like the skeleton of an organism. It principally used for safely carrying the maximum load for all designed operating conditions. Chassis frames should be strong enough to withstand the load and shock. Chassis is the foremost component of an automobile that acts as the frame to support the vehicle body. Hence the frame ought to be very rigid and robust enough to resist shocks vibrations and stresses acting on a moving vehicle. Steel in its numerous forms is commonly used material for producing chassis and overtime aluminum has acquired its use. However, in this study traditional materials are replaced with ultra light weight carbon fiber materials. High strength and low weight of carbon fibers makes it ideal for manufacturing automotive chassis. This study depicts the modal and static structural analysis of Ashok Leyland 3118il truck chassis frame for steel as well as carbon fibers. From the analyzed results, stress, strain and total deformation values were compared for both the materials. Since it is easy to analyze structural systems by finite element method, the chassis is modified using SOLIDWORKS 2016 and the Finite Element Analysis and Modal Analysis is performed on A workbench.
