Abstract
Truck industry is a major source of transportation in India. With an average truck travelling about 300 kilometers per day [1], every kilogram of truck weight is of concern to the industry in order to get the best out of the truck. The main objective of this project is to increase the payload capacity of automotive truck body. Every kilogram of increased vehicle weight will decrease the vehicle payload capacity in turn increasing the manufacturing cost and reducing the fuel economy by increase the fuel consumption. With the intension of weight reduction, standard truck body has been designed and analyzed in ANSYS software. C-cross section beams were used instead of conventional rectangular box sections to reduce the weight of the body. Light-weight Aluminum alloy Al 6061 T6 is used to increase the payload capacity. The strength of the Truck platform is monitored in terms of deformation and stress concentration. These parameters will be obtained in structural analysis test condition environment. For reducing the stress concentration the concept of beams of uniform strength is used. Accordingly necessary modifications are done so that the optimized model has a better stress distribution and much lesser weight compared to the conventional model. The results obtained by analyzing the modified model are compared with the standard model.
Highlights
Transport industry plays a crucial role in development of modern industrialized countries economy
There is a considerable focus on design of the truck body, for increasing payload capacity
Replacement of rectangular cross section beams with C-cross section beams, use of Aluminum alloys instead of structural steel will be the feasible solutions for increasing payload capacity of the truck
Summary
Transport industry plays a crucial role in development of modern industrialized countries economy. The total weight of the load carried on the truck has been increasing drastically. Today’s difficult challenge of transport vehicle is to meet the increasing demand for better performance, less weight and more reliability. All this criteria has to achieve in short duration of time. There is a considerable focus on design of the truck body, for increasing payload capacity. Replacement of rectangular cross section beams with C-cross section beams, use of Aluminum alloys instead of structural steel will be the feasible solutions for increasing payload capacity of the truck. With the use of aluminum the strength of the truck reduces, which can be augmented by using the concept of beams of uniform strength
