Abstract
The primary supporting structure of an automobile and its other vital systems is the chassis. The chassis structure is required to bear high shock, stresses, and vibration, and therefore it should possess adequate strength. The objective of current research is to analyze a heavy motor vehicle chassis using numerical and experimental methods. The CAD design and FE analysis is conducted using the ANSYS software. The design of the chassis is then optimized using Taguchi design of Experiments (DOE); the optimization techniques used are the central composite design (CCD) scheme and optimal space filling (OSF) design. Thereafter, sensitivity plots and response surface plots are generated. These plots allow us to determine the critical range of optimized chassis geometry values. The optimization results obtained from the CCD design scheme show that cross member 1 has a higher effect on the equivalent stresses as compared to cross members 2 and 3. The chassis mass reduction obtained from the CCD scheme is approximately 5.3%. The optimization results obtained from the OSF scheme shows that cross member 2 has a higher effect on equivalent stress as compared to cross members 1 and 3. The chassis mass reduction obtained from optimal space filling design scheme is approximately 4.35%.

Summary
The two important parts of a vehicle body are the chassis and bodywork, which constitute the maximum volume and weight. Have optimized the design of heavy vehicle chaschassis using the analytical target cascading (ATC) method. Sharma et al [19] conducted FE simulation on the TATA turbo SE 1613 determine stresses and deformation under heavy loading conditions. A limited number of studies have been conducted on the design and optimization of heavy commercial vehicles chassis frames. The designing of components is quite a critical process It requires optimization, which is often a trade-off between weight savings and the dynamic performance of those components. The objective of this current research is to analyze a heavy vehicle (truck) chassis using numerical and experimental methods. The section describes the methodology we followed in achieving the above
