Automotive chassis is designed to support all body components (body structure, lugged, riders, engine, transmission parts, and …….etc) and is in turn supported by the front and rear wheel suspension systems. Early cars and most modern commercial vehicles traditionally have had channel section chassis members. The chassis strength in all motion directions should be checked to have enough chassis stiffness. The chassis stiffness is important to limit the vehicle components handily characteristics. This article presents the stress and strain analysis for a truck chassis (ladder chassis) in a beam form. The truck chassis models analyzed using the finite element techniques. The chassis finite element models were checked for stiffness, deflection, shear and bending stresses, and strain by using MALAB software. The results of the checked models determine the critical location of the truck components on its chassis. Some modifications are also suggested to reduce the truck chassis failure.
