Structural Optimization Using FEA-DOE Hybrid Modeling- A Review

This review presents a thorough survey of academic work on the chassis design by FEA and application of design of experiment method in it. It surveys most literature published in English language. The review aims to provide insight into the truck chassis design and act as a guide for researchers working on both FEA and DOE method for chassis design. The main objective of the design is to obtain the optimum weight of the chassis. This optimum design is being constrained by the maximum stress, stiffness and the natural frequency requirements. The number of cross members, their locations, cross-section and the sizes of the side and the cross members becomes the design variables. As the chassis frame is analyzed using the finite element techniques, appropriate model of the frame is to be developed. Then by comparing them we can get the best solution. Since the no. of parameters and levels of parameters are more, the probable models are too many. So, to select optimum parameters among them large no of modeling and analysis work is involved which consumes more time. To overcome this problem design of experiment technique can use along with FEA.This document gives formatting guidelines for authors preparing papers for publication in the International Journal of Emerging Technology and Advanced Engineering The authors must follow the instructions given in the document for the papers to be published.
