Lightweight Design of the Truck Side Framework

Abstract:

For the vehicle, lightweight means low fuel consumption. and small quantity of exhausted gas. In this paper by using the finite element method, the author established the model of the truck side framework. After meshing, exerting constraint, loading and calculating through finite element analysis software,the author obtained the deformation of the component. By researching changes of the stress and strain in X, Y, Z three directions of the component,the author obtained chart of the stress and strain. By using the method of arithmetic, the author defined the internal dimension as design variables, the equivalent stress and the deformation as the state variables, and quality as the objective function to get the lightest side wall frame of the vehicle on the premise of warranty of the intensity and stiffness.From the result, we can see the framework after optimal design is still very strong to resist the stress and the deformation.
