Strengthening Automobile Chassis Using Finite Element Analysis

Posted by on

A chassis provides the much needed support to the vehicle body, and bears number of loads in order make sure that they do not get transmitted inside the cabin. In general, the chassis has to accommodate five loading conditions that include bending, torsion, combined bending and torsion, lateral and fore & aft loading. These loads generate due to vehicle motion, its maneuvering and uneven road conditions.

As such the chassis frame has to be designed to possess enough strength to withstand these loads without failure. It is obvious that the structural strength is dependent on material and design of the frames, but the increasing complexity in vehicle designs and the need to develop lightweight vehicles put a lot of strain on devising the right chassis frame that performs its task for a sufficiently long period of time without getting deformed.
