The closer the mass is located to the CoM (which, for argument’s sake, we will assume to be the axis of rotation), the lower rotational inertia the chassis displays. That ultimately means that the yawing moments generated by the chassis generate higher yaw accelerations and result in a sharper dynamic response. The chassis moment of inertia is important in defining yaw response. Placing big masses close to the CoM is key. [Jahee Campbell-Brennan] 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 As you design, it is important that you understand the demands placed upon your vehicle in the environment it is intended to operate in. If you consider that driving at 100 mph on a paved race circuit places far different demands on a vehicle than traveling at the same speed over a desert trail, then the ability to design or select components that match your needs becomes important.

Race car design is one of the most fascinating and yet one of the most complex aspects of the racing world. The design teams in the many motorsport categories are constantly developing new solutions with one single goal in mind: to make a car that, in combination with the driver, travels the distance of a circuit in an amount of time smaller than any other driver/vehicle combination present in the race venue at the day. But, how is this done? The first is that the reduced tendency to stall might produce a car that is more predictable to drive. And the more predictable a car is, the greater the driver's confidence.The changes mean teams have lost a lot of our ability to control one of the biggest problems for an F1 designer - the air coming off the front tyres. 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. As new articles on this subject are written, I will add them here in an organized manner, for your better experience.

For the car to perform at its optimum, it is important to have a good balance between how much the car pushes down on the front wheels, and how much it pushes down at the rear. One of the bold and dynamic racing fonts that I want to introduce to you is Asphalt Racer that is a perfect font to be used in sports equipment. This all caps font comes with alternative characters and ligatures. Use this font for your next design and enjoy it!

CFD/Wind tunnel evaluation – The concept is analysed using CFD and/or wind-tunnel testing to evaluate its potential benefits. The chassis balance is often assessed subjectively, but it does have very objective roots. In the most basic terms, chassis balance describes which axle loses grip first and leads to under or oversteer. The physics behind balance forms one of the fundamental equations of cornering, namely the concept of yaw moment equilibrium. Mercedes have reduced the size of their bargeboards this year. This might mean they are generating less downforce at the front of their floor, but it gives them lots of potential to create plenty of downforce at the rear with the diffuser.

I can't tell you my name, or where I work, because my team would not want me to be doing this. F1 is a secretive world. So let's just call me The Secret Aerodynamicist. For racing cars, the objectives are much more oriented toward pure performance. The primary objectives of most race cars or performance cars are: Wheel and suspension components and their association with the notorious ‘unsprung mass’ needs little introduction. However, the importance of this mass when associated with dynamics is perhaps less understood further than that it should be minimised.Depending on whether you are starting from scratch or a donor car (The “Design Start point”) or are designing with sanctioning body regulations or your own vision (The “Design Basis”), there are four possible variations in the car design process. Treatment of these chassis modes is significant in vehicle dynamics because each mode has a different impact on dynamic situations. With different responses, we should manage them separately. How does the F1 car do this? Part of it is an engine that produces close to 1,000bhp. But the difference in lap time is mainly made up of the F1 car's cornering abilities. And the main reason for them is aerodynamics. There are a lot of Cadillac design cues in the body lines of the DPi,” says Blanski. “The surface tension and line quality in the early sketches were inspired by the production vehicles in our studio.” Given that these unsprung components are continually accelerating, decelerating and changing the orientation of the rotational axis (steered wheels) during a lap, the sensitivity of the vehicle to these inertias becomes important.
