Definition: Chassis

Chassis is the physical framework that holds the various components of a product together. It supports the object and holds the components together.

Example of a chassis is an automotive chassis. The purpose of an automotive chassis is to hold all the different components of the vehicle together while driving. Also it transfers vertical and lateral loads, caused by accelerations through the suspension. Also it takes forces from the two wheels. The perfect chassis is made up of large diameter thin walled tubes. To understand the concepts and to design a chassis one must have a solid grasp of statics and deflection.

The Automotive chassis has two primary functions-

• Hold the weight of all the components

• To rigidly fix the suspension components together when in motion


The first goal is an easy design solution. It is also the basis of the original chassis designs that were taken directly from the horse drawn carriages. I-Beam and C-Beam are the most popularly used beams in Chassis designs. The frames in heavy vehicles like trucks still use this construction as it is an easy and effective method of supporting heavy loads.
