Analysis of mass reduction of body in white component by using linear regression prediction method

The main objective of this project is to find out the effect of a change in BIW component stiffness and the stress developed if the thickness of the component is changed. The effect of a BIW can only have an adverse effect on vehicle strength. These installations should be tested under severe cornering conditions to ensure the desired handling characteristics of a vehicle. The analysis has been done by using Beta CAE ANSA, MSC NASTRAN, and Beta CAE METAPOST software applications for Generative Structure Analysis. This analysis is done on the basis of constant change in thickness since the main motive of the BIW is achieved by bending it. After gathering the engineering data, the prediction of thickness for the respective bending stiffness of the bar is calculated using a linear regression technique. In this study, our main aim is to observe the stiffness behavior with respect to thickness of sheet metal and prediction of the thickness for a target stiffness using linear regression method.
