Fatigue and Stress Analysis of a Load Carrying Car Chassis with Reinforced Joint Using Finite Element Method
Abstract
In this article, a case study of a load-carrying vehicle chassis with various loading conditions in six
maneuvers has been conducted. These maneuvers include acceleration and deceleration in a loaded
and un-loaded situation, drops, pothole, turn, and sinusoidal obstacles. Finite element analysis has
been implemented in order to calculate stress distribution and fatigue life. Stress analysis indicated
that the joints stiffness is higher where the auxiliary profiles were utilized. However, this procedure is
cumbersome and auxiliary plates would be a more efficient strategy. The effects of using auxiliary
plates have been investigated in the fatigue and stress distribution of the aforementioned chassis. The
analysis revealed that the 300 mm drop has the maximum tension and accordingly embodies the
shortest fatigue life. Furthermore, for welding joints, three different strategies for geometry
configuration including welding bead, reinforcing plates, and extra auxiliary profiles under the welded
joints were assumed.
