FEM model of vehicle chassis

Structural analysis concerns the calculation of the vehicle's characteristic properties, magnitudes such as stifness or eigen frequencies. Such calculations are used to determine the drivability or comfort of the vehicle.

The required calculations are the outcome of the Finite Element Method (FEM) and more specifically the method's application in the study of Structural Dynamics. In any case, the manufacture and analysis of digital prototype, as with the other sectors of digital mechanics, reduce the costly manufacture and use of real experimental prototypes, in addition to the gained knowledge for the vehicle's functionalism.

 

The Finite Elements Analysis method starts with the pre-processing in which the CAD model is parametrized into finite elements, via specialized software.
