Fuel Cell Vehicle's Body Design Based On CAD Technique

The automobile industry represents the level of a nation' s manufacturing industry development. The economic developments of the economic giant of the world have great relationship with automobile industry. The best two company of automobile industry is also the best of the world business enterprises; it can explain nicely this point. Laying aside faraway Europe and America, just pay attention to our neighbor country of Asia, Japan with Korea is obtained fast development mainly at automobile and electronics these two greatest industries, so aroused whole national economy. Two factors of most that affect the automobile industry development are the energy and the transportation problem. Fossil fuel will dry up someday, early making fuel cell vehicle becoming a solid relating to our living, but is a not outcome to stay around the stage in laboratory any more is our current urgent mission. The fuel cell vehicle is a real green vehicle, it is a good choice to make us get away from two big problem -the environmental protection and the energy.The usage of the new power system wants to improve on the each system of the original vehicle by all means. This text carry through the design to the fuel cell vehicle body from this angle: Inherit originally possessed to the vehicle carriage, make use of the current resources; Rearrange to whole car afresh according to fuel cell vehicle's own characteristics at the same time, designing the new vehicle's construction. The main force of the manufacturing industry, the automobile industry has been applied vanguard in CAD/ CAM/ CAE system. Technical application in CAD pushed the developments of the vehicle manufacturing industry availably. This text use UG to set up the mold of vehicle's body and its parts.Firstly, this text introduces the international and local's fuel cell vehicle's present condition, the purpose and meaning of the text. We have the advantage of developing, realize the span type development of the social productivity, we must stand at the same line with our opponent. Develop 21 centuries' fuel cell vehicle, this will be the hope of the Chinese automobile industry. And the technique of CAD is the main means to lower the cost of development, and the design of the big automobile factory in the world is all to occupy the predominant position with the CAD application. Secondly, this text introduces some theories about NURBS curve. Then, this text introducesthis time to design the body and parts, considering about to conform the target parameters, to choose the material of the vehicle, electrical wheel's characteristics, the aerodynamically characteristic, human body engineering and so on. And then gets the result of the body' s shape. Finally, the text introduces the softwares of the now world and its development present condition; and the method and the technique using to get the result in detail.In the end, this text outlook development regulation and trends of the vehicle shape, and the foreground of the fuel cell vehicle.
