Construction of an F1 car


Construction of an F1 car


The race-day performance of an F1 car has already been determined at the design stage. The design process is a path of evolution to enhance strengths and eliminate weaknesses, all with the goal of developing the finest F1 machine in the world.
CAD department at Toyota
Working under Keizo Takahashi, general manager of car design and development, Toyota's design department uses CATIA's state-of-the-art computer-aided design (CAD) software. An F1 car has about 3,500 separate elements, the majority of which have to be designed separately but must fit together with the utmost precision.
But long before any of the details have been designed, an F1 team determines the overall philosophy for their car. The team must balance potentially conflicting spatial requirements of the engine and gearbox, while the suspension and the aerodynamics must be reconciled into a package that is quick, but not unwieldy to actually produce and repair.
Although F1 cars must conform to a minimum weight limit of 600kg, the advantage of building the car underweight is that the engineers can optimize it to suit individual circuits by mounting ballast on different parts of the chassis.

Speeding up work with a lasersinter 
The designers look to make many changes during the course of a season, whether to try out new aerodynamic parts or to accommodate changes to the engine or gearbox. A more powerful engine, for instance, will generate more heat, so the designers will have to improve heat dissipation - perhaps by installing larger radiators, or by finding more clever ways to vent the hot air aft of the radiators without impairing the aerodynamics. Designers also need to produce several variations of certain parts to suit specific circuits, including larger brake ducts for tracks that require heavy braking. Modern technology enables the designers to produce prototype parts easily, quickly and accurately. The composites department has a lasersinter machine that can produce high-quality parts in only a few hours. The lasersinter is a high-accuracy laser that selectively fuses together a polyamide powder to create the component. They do not have the structural strength of carbon fiber, but can be used in the wind tunnel or as molds for composite parts.

Chassis Construction

To achieve the highest standard of quality and consistency, Panasonic Toyota Racing uses the most sophisticated measuring equipment available. The machines in Toyota's CNC (Computerized Numerical Control) department can mill the smallest of components to an accuracy of four microns - about 25 times less than the width of a human hair - from a range of materials that include aluminum and magnesium. This is the sort of precision that F1 demands. As well as producing suspension and gearbox components, the CNC workshop makes the majority of the engine and many of the patterns that are used in the composites department to create the bodywork molds. In the composites department, the car as you recognize it begins to take shape.
Assembling an F1 car
Most structural composite components have an aluminum honeycomb core bonded with several layers of carbon fiber.
Step 1: Cutting A computer-controlled ultrasonic cutting machine slices precisely measured sheets of resin-impregnated carbon fiber cloth. Until it is cut, the carbon fiber has to be stored at - 18 °C, because it begins to harden at room temperature. An ultrasonic cutting machine is not a luxury- its speed and accuracy are vital. Some detailed cutting work is also performed by hand.
Step 2: Molding The cut sheets are laid into molds of predetermined patters in a special air-conditioned clean room. This pattern of interwoven matting is what gives the finished component its strength. The material is then put in a vacuum bag.

Step 3: Autoclave Once the parts have been put in a vacuum bag, they are moved to the autoclave. The autoclave is a sealed vessel that applies pressure (between two and six times normal atmospheric pressure) and heat. The pressure, combined with the vacuum bag, ensures that components fit the molds exactly, while the heat (usually between 130 and 140°C) hardens the resin. Since this process is computer controlled, the design team can change the programs as necessary.
Step 4: Assembly When finished, the parts are sent to the assembly division for finishing. Even parts formed to such precise specifications must be detailed by human hands to fit properly. This ensures that all parts can fit together properly. If drilling or other machining is required, the parts are sent back to the CNC division.

Engine Technology

Only two other F1 teams (Ferrari & Renault) constructs both its own engines and chassis. The close coordination between these two technical departments confers an advantage because it enables Panasonic Toyota Racing's designers and engineers to envision the car as a whole from the very first concept drawings. The word "drawing" is something of a misnomer, since the engines and chassis are designed on computers using CATIA CAD software. It takes around 1500 detailed "drawings" to make a complete engine.

Luka Marmorini, General Manager of the Engine Division

"Our facilities are state-of-the-art. We have all the tools and people we need. We have hired some young engineers, some people from within F1, and we have people who have worked on Toyota's rally and Le Mans programs. It is a good mix of experience." Achieving the correct balance of performance, reliability and weight requires a methodical approach.
The engineering test bench. The engine sits below the thick exhaust duct.Exhaust pipes are created by hand. It takes one technician 50 hours to complete one pipe, and each pipe only has a life of one race.

The mechanics working in the engine workshop build and rebuild around 300 engines a year.The rebuilding process is not merely reassembly; around 40 percent of the 4,500 components will have to be replaced by new ones. All in all, it's a 200-hour job. The engine department has eight dynamometers that perform pre-race checks. These simulations use actual race data, which lets the engineers recreate realistic conditions for an engine without it ever leaving the factory.
Marmorini "Our goal is to make several performance leaps during a season. Of course, we cannot sacrifice reliability, which is why we take such pain-staking measures in production and testing."

Aerodynamics

Hilhorst's team has been working 16 hour days since Toyota's wind tunnel became operational in early 2002.

A wind tunnel experiment in progress

Toyota's wind tunnel is capable of simulating speeds in excess of 200mph on a half-scale model of a car. The steel belt "rolling road" accurately simulates the movement of a real road beneath the car - even though the car is stationary in the wind tunnel.

CFD Simulations Conducted First

Since minute changes can affect the flow of air across the entire surface of the car, the aerodynamicists must prioritize their ideas. Often they will use computational fluid dynamics (CFD) software to test the effectiveness of potential improvements before actually designing and making a new part. This not only saves money, it also minimizes the risk of spending days or weeks researching changes that do not result in an improvement.
Aerodynamics division technicians make minute adjustments to a wind tunnel model car.Some aspects of a car's behavior are difficult to predict in software - pitch sensitivity, for instance, where the aerodynamics are adversely affected by the pitching of the car under acceleration and braking.
"CFD is useful," says a staff member, "but ultimately you must put your ideas to the test for real, either in the wind tunnel or out on track. If your preparation has been good, you will see the improvements."

Lamborghini Reventon


Lamborghini Reventon



Born in Sant’Agata Bolognese
The Lamborghini Reventón has been entirely designed in Sant’Agata Bolognese, the original birthplace of the Lamborghini and the native home of every super car born under the sign of the bull. The design drawn up in Lamborghini’s Centro Stile (Style Centre) is fine-tuned in close collaboration with the Lamborghini Research and Development Department. Thus, the Reventón is not only “haute couture” but it also stands out for its elevated dynamism whilst being entirely suitable for every day use.
The Lamborghini Reventón is not destined to remain a one-off. A total of 20 Lamborghini friends and collectors will be able to own this extraordinary car and, naturally, enjoy the incomparable pleasure of driving it.
The name Reventón has been chosen according to Lamborghini tradition. Reventón was a fighting bull, owned by the Don Rodriguez family. It is included in the list of the most famous bulls ever and is known for killing the famed bullfighter Felix Guzman in 1943.
Inspired by the fastest airplanes
The present day Lamborghini models are distinguished by the clear language of their shape. The coherent proportions of the Murciélago and Gallardo highlight their power and dynamism. Sharp edges, precise lines and clean surfaces: these are ingredients of a style reduced to the essential. Each element is created exactly according to its function; ornaments and decorations are totally foreign to a Lamborghini.
With the Reventón the Centro Stile designers have coherently developed this philosophy, inspired by another sphere where speed and dynamism reign absolute: modern aeronautics, responsible for the fastest and most agile airplanes in the world. This has created an extremely precise, technically striking style with a new vitality: interrupted lines and contorted surfaces create a fascinating play of light, giving the car incredible movement.
Made of carbon fibre and precision
Although it is based on the extraordinarily successful Murciélago LP640, the exterior design of the Reventón is completely new. Just like the base model, the exterior is made of CFC, a composite carbon fibre material, which is as stable as it is light. The exterior components are glued and fixed to the body comprised of CFC and steel.
The front is characterised by the acute angle of the central ‘arrow’ and by the powerful forward-facing air intakes. Although they do not supply air directly to the turbine like an airplane, bearing in mind the 650 hp, an abundant volume of air is necessary to cool the carbon brake disks and the six cylinder callipers.
Born to become a legend
Since its foundation, Lamborghini has been a creator of trends in the world of sports cars and has always manufactured cars with an absolutely unmistakable character. Models such as the Miura or Countach, for example, were veritable forerunners and rapidly acquired the status of timeless classic cars. From the moment they are launched, every new Lamborghini promises to become a legend, destined to become a sought-after and precious possession.
With the Lamborghini Reventón, Lamborghini has done it again; it has created an unequalled super car; the perfect synthesis between the exclusivity and appeal of a limited edition design masterpiece, and the dynamism and driveability of a standard sports car. Thus, the Lamborghini legend is further enhanced by another, stylish future classic.
