CAMS & FIA Rollcages

Rollcage Certification Using FEA

Bremar Automotion are approved by CAMS and the FIA to homologate motorsport rollcages using Finite Element Analysis (FEA), both in Australia and internationally. Any rollcage that does not fully comply with CAMS or FIA requirements must undergo the certification process, including the use of alternative materials such as chromoly.

Fully Validated Computer Modelling Methods

We have conducted a range of destructive physical tests on a full size rollcage and various welded joints to validate our computer modelling methods which has given us a high degree of confidence in our simulations and will help us provide you with a rollcage design that achieves the ultimate balance between safety and performance.

Detailed Tube & Joint Simulation

Our FEA models use a 3D shell modelling method which models the wall of the tube itself rather than the previously accepted 1D centre line modelling methods, to provide much more accurate stresses and deformations at the circumference of the tube, particularly around the welded joints. It also picks up on localised buckling of the tube surface which can play an important part in overall strength of the rollcage, particularly for thinner wall tubes as shown in the animations below.

Simplicity For Our Customers

Our rollcage data spreadsheet makes it easy for you to provide us with the necessary info about your rollcage dimensions, and then streamlines the computer modelling process to ensure fast turn around times. We also offer a 3D scanning service where we scan the vehicle interior and design a suitable rollcage directly in CAD, ensuring dimensional accuracy and eliminating trial and error fitments.

We can also perform physical tests for FIA certification of dismountable joints for bolt in rollcage applications, providing a true “one stop shop” for the design and homologation of motorsport rollcages and accessories.

Whether you’re looking for a rollcage with maximum strength, minimum weight, or an ideal balance between the two, contact us now to discuss your next rollcage design.
