ABSTRACT: Chassis Frame is major Load Carrying Structure of the Formula Racing Car, the main function of Chassis Frame
is to provide Mounting Points Location to assemble different sub-assemblies like engine, fuel tank, fuel filter, Suspension
system and bear the self-weight of vehicle and passenger. Vibrational Characteristics of chassis frame is very important
for providing proper stiffness to chassis frame to meet the Vehicle noise and durability requirements. It is designed to
Support all major sub-assemblies of vehicle. Chassis is major Component and backbone of Vehicle it serves the purpose of
carrying the full vehicle load under its operating conditions along with occupant weight . The main objectives of this work
is to design a new model chassis for two materials and to find the deformation and modal values of the structure. CAD
modeling is done by using CATIA and Finite Element analysis is done by using HYPERMESH V19 which includes all the
prepossessing activities like applying material properties and boundary conditions and static loads for structural analysis
using Optistruct. In the present work two materials are considered for the analysis and from these two materials result
obtained best materials is selected for chassis frame . Analysis results are validated with analytical result .

Key Words: Chassis, Catia Tool ,Optistruct, Modeling, Boundary Conditions, Hypermesh.
