Wunibald Kamm
Wunibald Kamm (April 26, 1893 – October 11, 1966) was an Automotive design, automobile designer, engineer, and aerodynamics, aerodynamicist. He is best known for his breakthrough in reducing car turbulence at high speeds; the style of car bodywork based on his research has come to be known as a Kammback or a Kamm-tail. Design One goal of automotive aerodynamics is to reduce the air turbulence, or Drag (physics), drag, caused by the shape of the automobile. Aerodynamic drag may be reduced either by reduction of frontal area or by reduction of drag coefficient. In bodies such as automobiles and airships, drag decreases after the rear of a car's cross-sectional area is reduced to fifty percent of the car's maximum cross section; "the best position is nearer 45 per cent of the length, and ... to have this maximum cross- section nearer the rear end than the front, and its drag has proved even less". There are other aspects of the car's design such as keeping the flow of air attache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedan (car)
A sedan or saloon (British English) is a passenger car in a three-box configuration with separate compartments for an engine, passengers, and cargo. The first recorded use of the word "sedan" in reference to an automobile body occurred in 1912. The name derives from the 17th-century litter known as a sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style include the close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan, and sedanet/sedanette. Definition A sedan () is a car with a closed body (i.e. a fixed metal roof) with the engine, passengers, and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles, but in practice, the typical characteristics of sedans are: * a B-pillar (between the front and rear windows) that supports the roof * two rows of seats * a three-box design with the engine at the front and the c ...

Vehicle Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for ...

Forschungsinstitut Für Kraftfahrwesen Und Fahrzeugmotoren Stuttgart
The Forschungsinstitut für Kraftfahrwesen und Fahrzeugmotoren Stuttgart (FKFS), (in English: Research Institute of Automotive Engineering and Vehicle Engines Stuttgart), is a private, nonprofit research and development institute for the automobile and supplier industry, focusing on vehicle technology, engine technology, and vehicle mechatronics. It was established in 1930, and called the "Kamm-Institut" after its founder and long-time director, Wunibald Kamm. At the institute, Dr. Kamm "built the first full-scale wind tunnel for motor vehicles." The institute was rebuilt after being destroyed in World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.

Research Institute Of Automotive Engineering And Vehicle Engines Stuttgart
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechatronics
Mechatronics engineering also called mechatronics, is an interdisciplinary branch of engineering that focuses on the integration of mechanical, electrical and electronic engineering systems, and also includes a combination of robotics, electronics, computer science, telecommunications, systems, control, and product engineering. As technology advances over time, various subfields of engineering have succeeded in both adapting and multiplying. The intention of mechatronics is to produce a design solution that unifies each of these various subfields. Originally, the field of mechatronics was intended to be nothing more than a combination of mechanics, electrical and electronics, hence the name being a portmanteau of the words "mechanics" and "electronics"; however, as the complexity of technical systems continued to evolve, the definition had been broadened to include more technical areas. The word ''mechatronics'' originated in Japanese-English and was created by Tetsuro Mori, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coil Spring
A selection of conical coil springs The most common type of spring is the coil spring, which is made out of a long piece of metal that is wound around itself. Coil springs were in use in Roman times, evidence of this can be found in bronze Fibulae - the clasps worn by Roman soldiers among others. These are quite commonly found in Roman archeological digs. Coil springs can be either compression springs, tension springs or torsion springs, depending on how they are wound. A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. They are commonly used in mattresses, automotive suspensions, and residential plumbing. Coil springs come in a variety of sizes and shapes and can be used for a variety of applications. Small coil springs are often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent Suspension
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump on the road) independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together. Most modern vehicles have independent front suspension (IFS). Many vehicles also have an independent rear suspension (IRS). IRS, as the name implies, has the rear wheels independently sprung. A fully independent suspension has an independent suspension on all wheels. Some early independent systems used swing axles, but modern systems use Chapman Chapman may refer to: Businesses * Chapman E ...

Flat Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with less than six cylinders) and V engines (for engin ...

Front Wheel Drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor. It then took at least a century, for the firs ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of whic ...
