Research And Markets: Analyses The Technology Of The Chassis Engineering And Systems Area In Detail.DUBLIN, Ireland -- Building on the success of our first edition chassis report, this new second edition is by respected and multiple award-winning author and analyst Jeff Daniels For other persons of this name, see . Jeffrey "Jeff" Warren Daniels (born February 19, 1955) is an American actor, musician and playwright. Biography Early life . Jeff's excellent report surveys the technology of the chassis engineering and systems area in detail, concentrating on the history, which has created the present situation, the range of current solutions, and the most likely ways forward at a supplier and OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and level. While the survey is mainly technical, it provides pointers to future system volumes where these are appropriate, and also concludes with brief surveys both of the main Tier-One suppliers and of the policies of the main surviving VMs with regard to chassis engineering. Research and Markets (http://www.researchandmarkets.com/reports/c12039) has announced the addition of A Global Technical And Manufacturer Review Of Automotive Chassis Systems - 2nd Edition to their offering The main pressures on vehicle designers and engineers continue to be safety and exhaust emissions, together with fuel economy (except in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. ). However, intense competition, especially towards the top of the market, means that comfort and sheer ease of driving are also important considerations. They can make the difference between winning and losing the customer. Consequently, a great deal of engineering effort has lately been devoted to the chassis - in its modern sense of suspension, brakes and steering - in a search for unparalleled levels of ride comfort & quietness, control and dynamic safety. The following is an extract from this report: "some observers regard chassis systems and suspension systems Noun 1. suspension system - a mechanical system of springs or shock absorbers connecting the wheels and axles to the chassis of a wheeled vehicle suspension as synonymous, but this disregards the interdependence in·ter·de·pen·dent adj. Mutually dependent: "Today, the mission of one institution can be accomplished only by recognizing that it lives in an interdependent world with conflicts and overlapping interests" of suspension, steering and braking systems and the fact that they are integrated to an increasing degree, especially at the electronic level. It may also be argued that even in the early days of motoring when complete chassis were delivered to coachbuilders for body installation, the steering and the brakes (such as they were) were already installed. Current scope In present-day terms, therefore, the terms "chassis engineering" or "chassis systems" embrace a hierarchy of technologies and features that may be outlined as follows: - Suspension: embracing the choice of basic geometry for optimum wheel location, the mounting of suspension members to the body (including the use of sub-frames), the springing medium and the provision of damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the of vertical wheel movement. - Steering: the optimisation of front suspension geometry for steering, the choice of steering system steering system, in automobiles, steering wheel, gears, linkages, and other components used to control the direction of a vehicle's motion. Because of friction between the front tires and the road, especially in parking, effort is required to turn the steering wheel. , the provision of power assistance, the satisfaction of safety requirements, and the provision of "augmented stability" through interaction with the braking system. - Braking: the choice of friction system, the design of the operating linkage linkage In mechanical engineering, a system of solid, usually metallic, links (bars) connected to two or more other links by pin joints (hinges), sliding joints, or ball-and-socket joints to form a closed chain or a series of closed chains. , the provision of servo An electromechanical device that uses feedback to provide precise starts and stops for such functions as the motors on a tape drive or the moving of an access arm on a disk. assistance, the satisfaction of safety requirements, the provision of anti-lock braking and other enhancements such as emergency brake assist Emergency Brake Assist (EBA) is a safety system in vehicles designed to ensure maximum braking power is used in an Emergency stop situation. By interpreting the speed and pressure at which the brake pedal is pushed, the system detects if the driver is trying to execute an emergency . - Wheels and tyres: choice of wheel and tyre Tyre (tīr), ancient city of Phoenicia, S of Sidon. It is the present-day Sur in Lebanon, a small town on a peninsula jutting into the Mediterranean from the mainland of Syria S of Beirut. size, choice of wheel material and tyre configuration, choice of spare wheel configuration or "run flat" technology. Other engineering constraints As noted in the outline above, chassis engineering is subject to many legislated safety requirements with profound engineering implications. Two examples are provided by the requirement (in almost all markets) to "split" the braking system in such a way that a single failure will not compromise safety, and the requirement that all steering systems (except in specialised vehicles with a low maximum speed) should consist entirely of mechanical linkages. In this latter respect, revised legislation will be needed, certainly within the EU, if "steer by wire" is ever to be acceptable. While the main engineering considerations in the area of chassis systems are as outlined above, design is also subject to the "universal" constraints of cost and weight. Reducing chassis engineering cost is especially difficult in the light of consumer demands for ever better refinement and ride comfort, and for higher vehicle performance (placing greater demands on the quality of steering, handling and roadholding roadholding Noun the extent to which a vehicle is stable and does not skid on bends or wet roads ). Electronic systems today play an increasing role in chassis systems, and this trend will continue into the foreseeable future. Most electronic systems add new capabilities, but also cost " The contents of this report are as follows: Chapter 1 Introduction Chapter 2 Chassis systems - definitions and significance Chapter 3 Suspension systems Chapter 4 Steering systems Chapter 5 Braking systems Chapter 6 Tier-1 suppliers Chapter 7 Manufacturer philosophies For more information visit http://www.researchandmarkets.com/reports/c12039 |
