Effect of Trapezoidal Geometry of Cross-Section of Annular Fin on Thermal Stresses and Strains

Automotive chassis design, development is quite important in today’s environment. This work is oriented towards analysis of a ladder chassis and space frame chassis design. The analysis of the designed models involves the use of three different materials. In this investigation two different conditions of vehicle loading are considered namely un-laden (without passengers that is the KERB weight of the vehicle) condition and the laden (with passengers and miscellaneous weight also called gross weight) condition. Analysis had resulted with various variables of stress indicating the stress levels minimum in unladen case as 3.00E-17 and maximum in laden case as 29.8662, in case of space frame analysis the stress in minimum for steel with laden chasis as 0.001558 and maximum in case of composite material as 7.8447. These results would be useful with in selection of material for automotive frames.
