Chassis is a most important part of vehicle. The chassis work as the backbone of a vehicle which carries the maximum load for all operating conditions. Work of the chassis is to gives a structural platform that can connect the front and rear suspension. Also, it must be hard enough to bear the shock, twist, vibration and other stresses caused because of sudden braking, acceleration, shocking road condition, centrifugal force while cornering and forces induced by its components. So, strength and stiffness are two main parameter for the design of the chassis. The current study has analyzed the Different literatures. After a analysis of dissimilar research paper studies carry so for it has been found that there is the scope of optimizing dissimilar point like load, stress-strain values and deformation etc. by varying cross sections and materials of chassis body. This paper describes the design, Structural analysis & optimization of the heavy vehicle chassis with constraints of peak stress, strain and deflection of chassis under maximum load. In the present work, the measurement of the TATA 2518 chassis is used for the structural evaluation of the heavy vehicle chassis with three different alloys subjected to the same position of the steel chassis. The three different material used for the chassis are selected as grey cast iron, AISI4130 alloy steel and ASTM A710 STEEL based on their easy availability and known characteristic. A three dimensional solid Modeled in the CAE software CREO and analyzed in ANSYS 14.0. The numerical results are validated with analytical calculation considering the stress distribution, deformation. Also two standard optimization techniques (Boxing & Reinforcement) are used to optimize the chassis frame.
