Racing Setup
In motorsport, the racing setup, car setup or vehicle setup is the set of adjustments made to the vehicle in order to optimize its behaviour (performance, Car handling, handling, reliability, etc.) for specific conditions. Vehicle setups are variable for a variety of reasons, ranging from weather, driver/rider preference and race track characteristics. Contrary to common misperceptions, setup is not used to maximize the performance of the engine, but to optimize it for the track at which it is being used. For example, motorcycle racers frequently detune their engines to reduce performance and power output so as to ensure the bike accelerates in a predictable manner. Usually adjustable vehicle parts include shock absorbers and anti-roll bar (Suspension (vehicle), suspension), gear ratios and Differential (mechanics), differential, Tire, tyre pressures and type, wing angles, wheel toe (automotive), toe and camber angle, brake bias, steering lock and ride height.

Aston Martin R-Motorsport Pitbox 2019 DTM Hockenheim
Aston is an area of inner Birmingham, in the county of the West Midlands (county), West Midlands, England. Located immediately to the north-west of Birmingham city centre, Central Birmingham, Aston constitutes a wards of the United Kingdom, ward within the metropolitan authority. It is approximately from Birmingham city centre, Birmingham City Centre. History Aston was first mentioned in the Domesday Book in 1086 as "Estone", having a mill, a priest and therefore probably a church, woodland and ploughland. The Church of SS Peter & Paul, Aston, Church of Saints Peter and Paul was built in medieval times to replace an earlier church. The body of the church was rebuilt by J. A. Chatwin during the period 1879 to 1890; the 15th-century tower and spire, which was partly rebuilt in 1776, being the only survivors of the medieval building. The ancient parish of Aston (known as Aston juxta Birmingham) was large. It was separated from the parish of Birmingham by AB Row, which currently e ...

Understeer And Oversteer
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of the vehicle to changes in steering angle associated with changes in lateral acceleration. This sensitivity is defined for a level road for a given steady state operating condition by the Society of Automotive Engineers (SAE) in document J670SAE International Surface Vehicle Recommended Practice, "Vehicle Dynamics Terminology", SAE Standard J670, Rev. 2008-01-24 and by the International Organization for Standardization The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries.

Coil Bind
{{Multiple image, direction=vertical, align=image1=BobbyLabonteCarApril2007.jpg, image2=Carl EdwardsTexasMotorSpeedway.jpg, width=265, caption1=At rest the air dam (red) of a car appears several inches above the ground., caption2=At full speed the air dam appears much closer to the ground. Coil bind is a style of setup used in various levels of NASCAR racing. Coil bind setups utilize very soft front springs and very stiff rear springs to control the pitch attitude of the body. This is in contrast with conventional setups which place the stiffer springs at the front of the car for superior mechanical grip, that is grip via the vehicle suspension and tires. Coil bind uses aerodynamics to produce grip. As a car approaches the end of a straightaway, the downforce generated by the body of the car should increase the sprung weight until the coil springs compress until they bind and the suspension can no longer travel (hence the name).

Car Tuning
Car tuning is the modification of a car to optimise it for a different set of performance requirements from those it was originally designed to meet. Most commonly this is higher engine performance and dynamic handling characteristics but cars may also be altered to provide better fuel economy, or smoother response. The goal when tuning is the improvement of a vehicle's overall performance in response to the user's needs. Often, tuning is done at the expense of emissions performance, component reliability and occupant comfort. As a culture has grown around modified cars the term tuning has grown to encompass the cosmetic and stylistic changes owners make to personalize their vehicles. These changes can range from functional modifications designed to improve the performance or functionality of the car, to visual modifications which alter the aesthetics of the car and, in the case of certain mods, sometimes be detrimental to the performance or functionality of the car.

Roll Couple
Roll may refer to: Physics and engineering * Rolling, a motion of two objects with respect to each-other such that the two stay in contact without sliding * Roll angle (or roll rotation), one of the 3 angular degrees of freedom of any stiff body (for example a vehicle), describing motion about the longitudinal axis ** Roll (aviation), one of the aircraft principal axes of rotation of an aircraft (angle of tilt to the left or right measured from the longitudinal axis) ** Roll (ship motion), one of the ship motions' principal axes of rotation of a ship (angle of tilt to the port or starboard measured from the longitudinal axis) * Rolling ''manoeuvre'', a manoeuvre of any stiff body (for example a vehicle) around its roll axis: ** Roll, an aerobatic maneuver with an airplane, usually referring to an aileron roll, but sometimes instead a barrel roll, rudder roll or slow roll ** Kayak roll, a maneuver used to right a capsized kayak ** Roll program, an aerodynamic maneuver performed ...

Roadholding
Road-holding – also written as roadholding and road holding – (in French being called "tenue de route", in German "Beibehaltung der Spur"), is essentially determined by the ability of a vehicle to stay on the road and on a desired trajectory of motion, whatever the circumstances (in curves, on greasy, wet or low-grip ground, loaded or not, etc.) may be, but also by the degree of ease that a driver may sense in controlling it in an emergency situation. (Hereby, the laws of nature as a framework, including the gravitational field of the planet Earth as well as the phenomenon of inertia, are tacitly assumed as given.) In the above context, the straight-line stability of a vehicle – which is concomitant with its ability to stay on a desired trajectory of motion – necessitates a certain degree of understeering. The capability to smooth down the road imperfections, affects both the comfort and the road-holding of a vehicle. To improve comfort in this regard means, basically, t ...

Rolling Resistance
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the Motion (physics), motion when a body (such as a ball, tire, or wheel) Rolling, rolls on a surface. It is mainly caused by Plasticity (physics), non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed. Two forms of this are hysteresis losses (see rolling resistance#Primary cause, below), and permanent plastic deformation, (plastic) deformation of the object or the surface (e.g. soil). Note that the frictional contact mechanics, slippage between the wheel and the surface also results in energy dissipation. Although some researchers have included this term in rolling resistance, some suggest that this dissipation term should be treated separately from rolling resistance because it is due to the applied torque to the wheel and the resultant slip between the wheel and ground, which is called ...

Body Roll
Body roll is the axial rotation of a vehicle’s body towards the outside of a turn. Body roll occurs because the compliance in vehicle suspension allows the vehicle body, which sits upon the suspension, to lean in the direction of the perceived centrifugal force acting upon the vehicle. Cause Vehicle suspension allows a vehicle’s wheels to move independently of its body. This smooths the ride for occupants and cargo while allowing the wheels to stay in contact with the ground over bumps. In a corner, the range of motion in the suspension allows the vehicle body to lean over toward the outside of the turn as the body tries to continue in a line tangential to the corner. Softer suspension with more travel will allow more body roll than harder suspension with less travel. Adverse effects Body roll allows a vehicle’s centre of mass to move towards the outside of the turn, increasing the load transfer to the outside wheels. This can cause understeer or oversteer to occur more e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roll Moment
Roll moment is a moment, which is a product of a force and a distance, that tends to cause a vehicle to roll, that is to rotate about its longitudinal axis. Landcraft In vehicle dynamics, the roll moment can be calculated as the product of three quantities: # the vehicle's sprung mass, the portion of its mass supported by the suspension, # whatever lateral acceleration that the vehicle is experiencing, usually centripetal acceleration from a turn, and # the vertical distance between the vehicle's roll axis and its center of mass. In two-axle vehicles, such as cars and some trucks, the roll axis may be found by connecting the roll center of each axle by a straight line. In single-track vehicles, such as bicycles and motorcycles, the roll axis may be found by connecting the contact patches of each tire by a straight line. Aircraft In aeronautics, the roll moment is the product of an aerodynamic force and the distance between where it is applied and the aircraft's center of mas ...

Spoiler (automotive)
A spoiler is an Automotive aerodynamics, automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across the body of a vehicle in motion, usually manifested as Spoiler (aeronautics), lift, turbulence, or drag. Spoilers on the front of a vehicle are often called air dams. Spoilers are frequently fitted to race car, race and high-performance sports cars, although they have also become common on passenger vehicles. Spoilers are added to cars primarily for styling and either have little aerodynamic benefit or worsen the aerodynamics. The term "spoiler" is often mistakenly used interchangeably with "wing". An automotive wing is designed to generate downforce as air passes around it, not simply disrupt existing airflow patterns. Rather than decreasing drag, automotive wings actually increase drag. Operation Aerodynamics plays a critical role in a car's behavior at higher speeds. Vehicles must be stable and balanced first at lower speeds t ...

Camber Angle
Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear. It is used in the creation of steering and suspension (vehicle), suspension. If the top of the wheel is further out than the bottom (that is, tilted away from the axle), it is called positive camber; if the bottom of the wheel is further out than the top, it is called negative camber. Effect on handling Camber angle alters the Automobile handling, handling qualities of some suspension designs; in particular, negative camber improves grip in corners especially with a Double wishbone suspension#Short long arms suspension, short long arms suspension. This is because it places the tire at a better angle to the road, transmitting the Centrifugal force#Examples, centrifugal forces through the vertical plane of the tire rather than through a Shear strength, shear force across i ...

Contact Patch
The contact patch is the portion of a vehicle's tire that is in actual contact with the road surface. It is commonly used in the discussion of pneumatic (i.e. pressurized) tires, where the term is used strictly to describe the portion of the tire's tread that touches the road surface. The term “footprint” is used almost synonymously. Solid wheels also exhibit a contact patch which is generally smaller than the pneumatic “footprint”. Contact patch size The contact patch is the only connection between the road and the vehicle. Pneumatic rubber tires The size and shape of the contact patch, as well as the pressure distribution within the contact patch, are important to the ride qualities and handling characteristics of a vehicle. Since the wear characteristics of tires is a highly competitive area between tire manufacturers, a lot of the research done concerning the contact patch is considered highly proprietary and, therefore, very little is published on the subject.
