SEMINAR ON F1 CARS

1. SEMINAR ON F1 CARS

2. Introduction • Most sophisticated vehicles used in the most technologically advanced form of sports. • Each and every minute details tuned to perfection • Each f1 team has the responsibility to come up with the most efficient design. • Bringing the f1 cars to a halt is an incredible challenge. • F1 car driving demands precision, incredibly fast reflexes and endurance from the driver.

3. The Chassis • Characteristics • Single seat cars • Open cockpit • Open wheels • Wings at front and rear • Position of the engine is behind the driver

4. The Cockpit • Cockpit is a very sparse environment. • Driver has limited movement. • Driver experiences G-forces. • Designers are forever trying to lower the centre of gravity of the car.

5. Aerodynamics • Wing theory • Rear wing • Front wing • Barge boards • Diffuser

6. Wing theory • Uses the same principle as an aircraft. • Aircraft uses lift whereas f1 cars uses down-force. • Drag- another important factor on an f1 car.

7. Rear wing • Made up of 2 sets of aerofoil connected to each other by wing endplates. • Top aerofoil made up of a maximum of 3 elements. • Lower aerofoil made up of single element. • Endplates prevent the air from spilling over the sides of the wings.

8. Front wing • Asymmetrical wing flaps on either side of the nose cones. • Asymmetrical shape allows better airflow increasing down-force. • Inside edges of the front wing endplates curved.

9. Barge-boards • Mounted between front wheels and side-pods. • Can be situated in the suspension. • Main purpose- Smoothen and direct the airflow coming from the front wheels. • They have contours to direct airflow in different directions.

10. Diffuser • Situated at the underside of the car behind the rear axle line. • Consists of many tunnels and splitters to control airflow. • Maximizes suction effect thus increasing down-force.

11. Engine • Ten times horse-power of a normal road car. • Operate at very high temperatures. • Limited to 3 litre, normally with 10 cylinders. • Engines made from forged aluminium. • Some components made from ceramics in order to reduce internal inertia of moving parts.

12. What makes these engines different to road car engines? • Air-box • Fuel and fuel tank • Exhausts • Cooling systems • Transmissions • Clutch • Gearbox • Gear ratios • Differential

13. Tyres • Must be able to withstand very high stresses and temperatures. • Tyres filled with special nitrogen rich, moisture free gas. • Tyres made up of 4 ingredients- carbon blacks, polymers, oils and curatives. • 3 types of tyres are used • Dry tyre • Intermediate tyre • Wet tyre

15. The Suspensions • Two forms of suspension. • Traditional coil spring setup. • Torsion bar setup • Both forms are mounted on the chassis.

16. Dampers • Often called shock absorbers. • Main purpose is to prevent the spring from oscillating too much • These dampers can be tuned to alter the handling.

17. The Brakes • F1 cars use disc brakes designed to work at 750 degrees celcius. • Brakes are set up with 60% braking force to the front and 40% to the rear. • Drivers are able to adjust the balance btw front and rear braking force from a dial in the cockpit. • Rotating discs are gripped by caliper squeezing the disc. • Discs are drilled for airflow to keep temperature down. • Front and rear braking systems are connected separately

18. Steering wheel and pedals • A sophisticated steering wheel with all the information available. • On the front of the wheel items such as rev lights, speed limit button, fuel mixture controls, radio buttons etc. are provided. • Levers for changing gears are located on the back of the wheel. • Pedals are designed specifically for each driver. • Only 2 pedals are available- for acceleration and for braking.

Design costs include the making of models, using the wind tunnel and paying crash test expenses etc. The cost of producing the final product will be €7,700,000

21. Random facts about f1 • In an f1 engine revving at 18000rpm, piston travels up and down 300 times a second. • If a connecting rod let go of its piston at max speed, the piston would have enough energy to travel vertically over 100 metres. • If a water hose were to blow off, complete cooling system would empty in just over a second. • F1 cars have 3 built in pneumatic jacks. • F1 car has as many as 8 radios operating at a time.

22. Conclusion • The car’s engine, suspension, aerodynamics, tyres etc determine how fast they go. • The engineering of materials, cooling system, aerodynamics and high temperature structural stiffness of f1 components is leading edge technology. • Getting the car tuned up and keeping it in a state of perfection are 2 of the team’s most important tasks during a season.
