- 3. ABSTRACT Automobile chassis is one of the major elements of road motor vehicles. Normally automobile is divided into two parts they are Body and Chassis. Thus this chassis design & analysis forms the most important stage of vehicle manufacturing. Chassis is a basic structure of a vehicle and is the integral part of the vehicle which bears the entire load of vehicle including its self-weight. Weight of chassis is one of the major influencing factor & it must be strong enough to resist shocks, twist, vibrations and stresses.
- 4. JUSTIFICATION OF TITLE In designing of chassis frame maximum stress and maximum deflections are the important factors. Static analysis of chassis is carried out by finite element method and the results like stress & deformation were obtained . The most suitable method for analysis is finite element method. A three dimensional chassis model is created in Creo 5.0 imposed in ANSYS 18.2. Finite element analysis truck chassis was carried out using ANSYS & its static behaviour was studied taking 3 different types of materials like Carbon/ Epoxy, Titanium alloy, Carbon steel.
- 5. OBJECTIVES • The main objective is to determine Maximum Stress Maximum Deflection • To recognize critical regions under static loading conditions. • Static structural analysis of Chassis is carried out by Finite Element Analysis method
- 6. METHODOLOGY • This study has been dealt with two parts. First part of this study involves modeling of chassis frame and analysis of stresses and displacement under actual load conditions. • CAD models of chassis frame were developed in 3D modeling software, such as Creo (Pro-E) 5.0. • The stress analysis and stiffness of the models are then obtained in ANSYS WORKBENCH 18.2. While the second part is shape optimization as weight or mass reduction purpose utilizing solid. Weight of the proposed design of chassis frame is then being compared to the current component that have been used for the previous existing chassis model . Evaluate

- 8. REQUIREMENTS • To carry the stationary loads attached to it and loads of passenger and cargo carried in it. • To withstand torsional vibration caused by the movement of the vehicle. • To withstand the centrifugal force caused by cornering of vehicle. • To control the vibration caused by the running of the vehicle. • To withstand bending stresses due to rise and fall of the front and rear axles.
- 9. APPLICATIONS • It can be used in Cars. • It can be used in heavy duty vehicles like Trucks etc. • It can be used in all types of vehicles where ladder type chassis is used.
- 10. SCOPE • Improvement of Truck chassis by changing the geometry, material & structure to the existing model. • This study is concentrate on Truck chassis of not more than 25 tons pay load. • Simulation & experimental work on the existing Truck chassis. • Development of new Truck chassis.
