Truck chassis is to provide structural integrity and stability to the commercial vehicle. In addition to supporting various components like, transmission system, body frames and payload to be placed upon it. Normally High strength low carbon steel is used as a main chassis material of heavy-duty trucks in our country in which the overall weight of the chassis is increased by 7% for reducing the deflection under load condition, road shocks to increase the stiffness of chassis. Due to this the gross weight of the vehicle is also increased. In this project, Aluminum lithium alloy is used as the alternative chassis material for heavy duty truck. In this Aluminum lithium alloy, 1% percentage of Lithium added to Aluminum reduces the density of material by 3% and increase in elastic modulus up to 7%. For a chassis frame thickness of 6 mm the Aluminum lithium alloy 2090 has the ability to give high strength with low density over high strength low carbon steel alloy. By using this aluminum lithium alloy we can be able to reduce one third of gross weight of vehicle chassis frame while compared to present chassis frame material. The modeling of the heavy duty truck chassis (Ashok Leyland Comet 1616 H) done by using Pro-E and The comparison of stress distribution and dynamic behavior like natural frequency of truck chassis made of high strength low carbon steel alloy and aluminum lithium alloy 2090 is done by using ANSYS software.
