Twist Beam Rear Suspension - Influencies of the Cross Section Member Geometry in the Elastokinematics Behavior

Nowadays the torsion beam rear suspensions have become a tendency in light commercial vehicles due to its simplicity and manufacturing low cost, allied to its packaging and functionality.

The elastic properties of this type of suspension determine its performance. The present work has as main objective, to study the influence of the geometry of the cross section member in the wheel travel behavior of the suspension, using the finite element method (FEM) as a tool.
