#### Abstract

The thesis entitled "Design and strength calculations of a composite shell body for an electric Formula Student car" describes the process of designing a body made of a sandwich composite for a vehicle participating in the international Formula Student competition. The first part of the work presents guidelines for the competition regulations, which should be taken into account when designing the load-bearing structure of the vehicle. It also describes the strength tests and analyses to be performed in the case of the use of composite materials in the body structure. The following chapter describes the load-bearing structures used in Formula Student vehicles. The general characteristics of materials used in the production of the described structures and micromechanics of the composite are presented. The comparison of disadvantages and advantages of particular types of bodies was made and the notion of torsional stiffness was approximated. The next part of the paper is a description of shell body modeling with the use of commercial software Siemens NX11. The proposed model was created taking into account the defined basic parameters of the vehicle and ensuring compatibility with the car components of Proton Dynamic. The properties of materials used in the construction of monocoque were described and the number of component layers of the sandwich composite was determined. The main part of the paper concerns the strength calculations of a sample of sandwich composite reflecting the side structure of monocoque, which is one of the requirements of the Formula Student competition regulations. The calculations were performed using Ansys Workbench software. The strength properties of the composite material were determined and the method of analytical calculations and MES of displacement of the sandwich composite sample subjected to load was proposed. The paper also describes the influence of boundary conditions and arrangement of sandwich composite component layers on displacement values. Then, for the designed monocoque car body, torsional stiffness was calculated and compared with the result obtained for the Proton Dynamic steel spatial frame. Additionally, the displacement of the structure caused by the load from the weight of the driver and the person standing on the analyzed object was determined. The final part of the work includes a summary of the results obtained and the prospects for the development of the project.
