Strength calculations of the Formula 1 car survival cell

Abstract

The paper presents the results of calculations by the finite element method (FEM) of the monocoque survival cell of a Formula 1 car designed with the use of a sandwich structure in accordance with the Formula 1 Technical Regulations of 2020. The guidelines for the chamber geometry and the necessary certification tests were presented. Proposed solutions in the field of materials for the design of sandwich panels, including cladding made of carbon fiber reinforced laminates and honeycomb cores made of aluminum and titanium. The results of computer simulations were discussed. The analysis of the obtained results of numerical calculations shows that the height of the cell filler has the greatest impact on the strength of the analyzed structure.
