Description
Summary:The material in the field of the transportation industry has changed dramatically. The chassis is an important and integral part of any vehicle all the components like steering wheels suspension etc. are attached to the chassis only. The purpose of the research work is to get results via simulation on a ladder frame chassis By changing the material of the chassis from structural Steel to carbon fiber and comparing both the simulation result. The research work is conducted in several stages were first part that is the design of the chassis has been done in SolidWorks then the modeling of the chassis has been accomplished in the ANSYS ACP module as well as the analysis of both deformation, stress, and strain energy has been done on the ANSYS workbench. The key study points are the maximum principal stress, von-mises stress, directional deformation, total deformation, and Strain Energy. Ongoing through parametric optimization and considering input parameters mesh element size, face sizing element size, and forces in all directions we concluded that the factor of safety for Structural Steel is less than that of carbon fiber. At -15000 N (downwards) the FoS is 12.212 for structural steel chassis and 14.158 for Carbon fiber/Epoxy Chassis. The result indicates that carbon fiber/epoxy chassis and structural steel chassis deformations having principle stress and von-mises stress-induced 47.88% and 40% less respectively in carbon fiber/epoxy chassis compared to structural steel chassis. And strain energy is 62.10% less in carbon fiber/epoxy chassis compared to structural steel chassis. Finally, this study reveals that, by using carbon fiber material, 70.60% weight reduction has been achieved without affecting strength, stiffness, and load-bearing capability.
