DESIGN OF THE STRENGTHENED FRAMEWORK FOR A DESIGNED CONCEPT OF THE SPORT CAR BODY

This paper presents design process and checking of the static stiffness of a sport car chassis at the conceptual design stage. Based on the requirement list, the concept of car body is designed, which is then analyzed from the point of aerodynamics, i.e. CFD analysis. With the analysis is determined that the car body is exposed to predominantly laminar flow of fluid with the presence of turbulent flow in the rear part of the car body. According to the data obtained from the aerodynamic analysis, the construction of the chassis is started. The chassis is the central supporting part of the overall car construction, which by its shape needs to follow outer contours of the car body. The chassis is reinforced with front and lateral attenuators. Attenuators are absorbing the energy that is releasing from strike.
