Structural Analysis of Chassis Frame Using CFRP and ANSYS Software

Abstract

Abstract: Automotive chassis is an important part of an automobile. The chassis serves as a frame work for supporting the body and different parts of the automobile. The chassis frame has to withstand the stresses developed within a limit. Along with strength, an important consideration in chassis design is to have adequate bending stiffness for better handling characteristics. So, strength and stiffness are two important criteria for the design of the chassis. This work is aimed at work performed towards the static structural analysis of the automobile chassis in which study of the stresses developed and deformation of chassis frame of a truck has been done . The chassis is modelled in SolidWorks and finite element analysis has been done in ANSYS. a comparison of current conventional steel chassis structural Steel and Aluminum and CFRP chassis in terms of deflection and stresses must be made in order to select the best one. A discussion and analysis is also done which gives insight on various effects of unidirectional fiber orientations in the chassis on strength and stiffness.
