This thesis includes an investigation into the mounting points of a Roll Cage on car frame using finite element methods. On most of motorsports competitions vehicles or military purposes vehicles it is compulsory or highly recommended to fit a Roll Cage to the vehicle to prevent major damage of the car and protecting the occupants in the event of a roll-over accident. A critical point in the design of a roll cage is the mounting points where the device is attached to the vehicle. A bad design of that part can result on a poor behaviour of the protection system on a crash event. Beam element model is constructed from a wireframe geometry of a representative roll cage to quantify the forces that the attachments points receive on a typical FIA test. Then, FE models of different mountings configurations are created and parametrical study is performed in order to provide guidance on how to improve mountings performance. Tests of two mountings specimens are carried to validate the FE models using a Rig created for this work.
