Race Car Design

Product Information

However, it is not just about piling on as much downforce as possible. An F1 car has to work in a number of different conditions, and it is never a perfect scenario.

On the side view sketch, front and rear axle centrelines are drawn together with the ground line and the undertray line, thus defining the ground clearance of the car. On the top view, a rough estimation of the location of major components such as engine, gearbox, fuel, water and oil tanks, radiators, seats, and minor components, such as pedals, gear lever, pipes an throttle cable is made. The Design of a vehicle is an iterative process where you attempt to meet all objectives you have defined. In practice, you usually won’t meet all of them, but hopefully most. Performance goals can also be set in relation to specific systems, as opposed to the whole car. For example, the goals for aerodynamics might include a specific value for the lift/drag ratio, and the location of the center of pressure (CP), while goals for the suspension might include a specific value for roll sensitivity, weight transfer, suspension travel, steer and camber variations and so on. In the vehicle dynamics world, we refer to chassis modes. Modes are combinations of wheel deflections that produce a particular form of chassis displacement. Traditionally these modes are discussed concerning road inputs, but the concept is also used to illustrate chassis displacements caused by longitudinal and lateral forces generated whilst driving.Generally, on circuit racing cars, locating heavy powertrain components close to the centre of mass is standard practice to keep the yaw inertia as low as possible. At this stage, the design team should look at the constraints imposed on the vehicle. The constraints are the practical limits within which the team should work on. The primary constraints should be the category technical and sports regulations. The designer must be completely aware of these rules and the limitations imposed by them. Also, it might be the case that costs and work force restrictions are imposed either by regulations, or by a limited budget. One good example is the 2-week shutdown that occurs in Formula 1, due to an agreement done by Formula One Teams Association (FOTA) intended to reduce the costs of running a competitive team. As new articles on this subject are written, I will add them here in an organized manner, for your better experience. The approach is made of six steps, namely, Analyses, Constraints and Goals Specification, Preliminary Design, Detailed design, Testing and Development. These steps will normally happen in a non-sequential manner, with some restrictions arising in later steps demanding changes in previous stages. A decade ago, Saward was project manager on the Furai programme, creating the beautiful concept car that met a fiery end during a magazine test. There are hints of its swoopy lines, too, in the new DPi.

CFD/Wind tunnel evaluation – The concept is analysed using CFD and/or wind-tunnel testing to evaluate its potential benefits. MDM Designs create stand out vehicle liveries for racing vehicles in all different types of disciplines. Designs can range from Formula Cars, GT Cars, Touring Cars, Transporters and more!

There is a direct analogy to this in the side view where the roll centre concept can be applied to the Pitch centre. Here, it’s anti-squat and anti-dive geometry that controls the location of pitch and dive centres, as described in the kinematics article.

At this point, individual parts will begin to be designed. The first step is to incorporate a Failure Modes and Effects Analysis (FMEA) to the component design. In this analysis, several failure modes for a part (or system) are listed, and the design team should arbitrate values to quantify the probability of a specific failure mode to occur, the chance of it being detected and the severity of that particular failure mode (failure consequences). These three parameters will be reflected in a score that represents how relevant a particular failure mode will be, helping to identify in which failures the design team should expend more energy. Blanski’s involvement extended beyond the Cadillac DPi’s body shape to details like the large, vertical daytime running lights, the valve covers for the Earnhardt Childress Racing Engines-built, 6.2-litre V8 motor and even the deep-dish wheels, which mimic the style of those found on a CTS-V road car. The design options available can cater anywhere from just a 'Side' view, all the way up to a complete all round design that includes both sides, front, rear and plan views to cover all possible perspectives of the vehicle livery design.Handling – The race car should have good enough control capabilities to allow the drive to operate it at the limits of the g-g diagram. This includes specifying details for some control systems such as steering, suspension, and other parameters. There is much more analysis that could be done at this stage toward optimizing the preliminary design. In the beginning of this stage, a lot of information will be available from the preliminary design. This information should be confronted with the design goals. Examples of data available from the preliminary design include the ones below: The area beside the driver, at the front of the sidepods, around what we call in F1 the 'barge boards', can produce a lot of downforce. The barge boards are the curved pieces that jut out from the main body of the car, and which direct the airflow in ways the designers want it to go. The process itself is really not that complicated, but it does require some patience if you are scratch-building. Donor car builders will find their job a little easier in that the components the car comes with usually limit the design options and therefore the number of iterations necessary to get the best design possible. Design Process Variations We had developed the LM55 Vision Gran Turismo for the PlayStation video game,” he says. “We wanted to put some of the design and styling cues from that into the RT24-P DPi.”

For racing cars, the objectives are much more oriented toward pure performance. The primary objectives of most race cars or performance cars are:The detailed design process includes constant solution proposal to specific problems and analysis of these solutions. These efforts should be run in parallel, since data from one is required to conclude the other. The proposal of new solutions might follow the engineering design process, which consists of the following steps: Practical observation and research ties our book knowledge to real-world examples. For instance, if you are designing a rally car, then researching the material, tube diameter and structure of a typical rally roll cage will enable you to tie your basic engineering knowledge to a practical example. Given even more practical examples of roll cages, you could use your knowledge to build a roll cage for your car and potentially even for other types of cars. The best practical examples are from vehicles that closely match the weight, speed and operating environment of your car. Testing/Verification The FASTRACE font has a steel style, and there is a diagonal line in each of the letters that you can use to design car, motorcycle racing posters. It is also suitable for designing action movies and racing posters. Car design is a process that begins with a vision or concept of the vehicle to be created. Much like production vehicle design, DIY car design seeks to define goals and objectives for the design. In passenger vehicles, the objectives are usually around price, acceptable performance and safety and satisfying the transportation needs of the target market. Common Race or Performance Vehicle Objectives If you are designing a car from a donor car chassis, your process will involve determining how the vehicle components can be changed to meet your vision/objectives. If you are designing from scratch, your process will involve the design and selection of components from the rubber on the road on up. Iterations
