How to Strengthen Vehicular Chassis Using Finite Element Analysis

Home » News » How to Strengthen Vehicular Chassis Using Finite Element Analysis

Finite Element Analysis (FEA) has been the go-to where prototype modeling and testing for a few years now. Despite being a virtual software, it provides life-like assessments of whether a design would work, and enables sectors to reduce the number of trials a physical model must go through.

Here’s how FEA works to produce enduring automobile chassis frames.

What is A Chassis Frame?

 Chassis is a frame that makes it possible for a vehicle to perform different functions like bending, maneuvering, and making it past bumpy roads in one piece, and keeping as much of the action outside as possible.


Due to these functions, the frame has to be strong enough not to fall apart or get deformed. Therefore, it needs to:

  1. Be created with strong materials.
  2. Designed accordingly

Since the modern vehicle is light in weight, the frame material needs to promise strength without heaviness. It has to bend in the right places, and remain unscathed despite the harshest road conditions.

Why Go for ANSYS FEA?

Here’s why having a mechanical design engineer model and test frames on ANSYS FEA might be better for car manufacturers.

  • They can experiment with unavailable materials.
  • They won’t have to keep making different chassis prototypes to test strength, safety, and flexibility because they can just do all that with the virtual model.
  • Therefore, they can finalize the virtual prototype and have the actual 3D printed prototype no more than once.
  • It’s an analysis run by the software, meaning they won’t have to detect problems in the structural design; the computer will do it for them. All they have to do is fix what comes across as broken.
  • They won’t have to spend much time in development, and can head straight to production.

Testing Chassis Strength with FEA

Cars aren’t half as expensive as the work that goes into making them. However, it used to cost manufacturers even more in the past. Thanks to FEA, they can use software to detect the structural deficiencies of a design instead of testing on an actual prototype over and over again.

They do this by creating a virtual 3D model. As per the FEA, they turn this model into several finite elements at critical junctures to test realistic physical constraints of the design. Next comes testing the frame under all possible external forces, such as speed bumps, uneven roads, wind, and so on.

The software’s job is to pinpoint where the design falls short so that manufacturers can bring it up to speed. They keep doing this until the design’s perfect, and then move on to actual trials.
