【正文】 從最初的箱式車身發(fā)展到四十年代的甲殼式。從汽車行駛速度造成的空氣阻力來看，汽車的百年發(fā)展史，其實質就是汽車如何克服氣動阻力的發(fā)展過程，車身的造型進步則生動的演繹著這個變化經歷。隨著電子技術的廣泛使用，結構緊奏強度高的流線型轎車現已大量行駛在道路上。70年代的能源危機使小巧玲戲的輕型轎車狠狠地賺了一筆，把曰本等推上了經濟大國的地位。四、五十年代軍車大出風頭，為了打贏第二次世界大戰(zhàn), 各式戰(zhàn)爭用車，如吉普、牽引車、富秋莎炮車紛紛涌向戰(zhàn)場。那時能獲的一輛封閉式車身的汽車就是用戶的最大心愿。特別是汽車制造工業(yè)水淮的高低。s duty is according to high air operated stable and the low aerodynamical resistance streamline form request, pletes the practical vehicle type finally the whole arrangement. Because gives dual attention to partial and the whole optimized design, causes the automobile body esthetic sense and the scientific nature achieves the harmonious unification, thus pursue automobile body modelling perfect and optimization.車身設計的演變和發(fā)展人們總習慣以藝術的觀點欣賞汽車的外型，而汽車猶如一個個流動的精度建筑物游戈在道路上，優(yōu)美的車身往往給人留下難以忘懷的印象。s manufacture technology, the human body engineering, esthetics and other related discipline various aspects requests, based on this and makes automobile body39。s development research stress point is the optimized design, may divide into two aspects on the whole the technical work: First, air operated shape partial optimized design, on the other hand is the air operated shape whole optimization design. The former duty is determined that automobile body39。s pressure difference lifts, the people in the rear part added has installed narrow and the micro on warp harassment, by was balanced the pressure difference, has solved when the high speed travel tailstock39。s about air current bad function, has increased front39。 second, underneath passenger vehicle39。s extension sunflower operation stability, has increased the anticrosswind ability and the straight line travel stability.In order to overe the ordinary fish keel type passenger vehicle in the high speed travel time front end vehicle39。s layered air current symmetrically, but tailstock39。s deep research, as well as the high efficiency greatly straight wind tunnel appears with the massive model of motor car experiment，One kind of more ideal wedge automobile body modelling appears in the auto market, is also the shoptalk is called the projectile the type automobile. This kind of shape39。s stable big enhancement, the anticrosswind ability also enhancement, the rear part whirlpool region obviously reduces, still basically continues to use this kind of modelling until the now majority enclosed body. Enhances along with the passenger vehicle high performance39。s center of mass drop, automobile body39。s carapace type automobile body, is obtains the present age aerodynamics to develop in the airplane wing design application enlightenment, its aerodynamical resistance coefficient pared to the vantype body large scale drop 1520 percentage points, has achieved 0, 450, 5 levels, liberates 6070km/h all of a sudden the vehicle speed. But further enhances along with the vehicle speed, discovers the bulge the beetle automobile body rear part, when the automobile goes will form the big whirling current area, will cause the automobile not to be suitable makes the high speed travel, but at that time this already was a very big leap. Afterward several dozens year technology advancement, the enclosed body surmounted the hull shape automobile body39。s widespread use, the structure played the intensity high streamline form passenger vehicle already massively to go tightly on the path. Look forward to the future, after the 21st century, each kind the passenger vehicle which has the distinct individuality characteristic, the colorful style to vary the convention now in front of the mon people.The air drag creates which from the automobile moving velocity looked that, the automobile hundred years history, how its essence is the automobile overes the aerodynamical resistance the developing process, the automobile body modelling progresses then vivid deductive this change experience. Enhances along with the passenger vehicle high performance request and the moving velocity further, the transpiration air current in the chassis base, sneaks in all directions in the different shape part, justs like each one small funnel and the sail, the serious hindrance automobile fast front moves, and the air current also can cause the chassis base to produce like flies the wing to raise the lifting force, but the wind tunnel appears with the massive model of motor car experiment, one kind of more ideal wedge automobile body modelling appears in the auto market, also is the shoptalk is called the projectile type the part this kind of shape automobile body the air current can have a negative lift, but on the automobile body is straightened out clearly along the chassis turn porch layered air current symmetrically, but tailstock turbulent flow then is greatly the reduction, creates the automobile body surface gas intensity of pressure distribution to be balanced, is helpful to the solution aerodynamical resistance and the aerodynamic lift the wheel to stress the malpractice which ability reduced falls, under the effective enhancement highvelocity current extension sunflower operation stability, has increased the anticrosswind ability and the straight line travel stability.The air current shape development studies the stress point is the optimized design, May not exaggerate said that in promoted automobile body39。s energy crisis caused the exquisite Ling play39。s automobile is user39。s automobile body modelling is one time social politics, the economy and the culture and so on various vivid synthesis reflected, also distinctively opens projects this time the entire industry horizontal and the plete regulation situation. Specially automobile factory industry Shui Huai height. before 1913, from the automobile birth, the automobile body thousand is the lignin horsedrawn vehicle39。s evolution and developsThe people are always familiar with by the artistic viewpoint appreciate automobile39。最后，再次感謝在大學四年里，曾經關心我?guī)椭业睦蠋熀屯瑢W們。同時也要感謝朱志強老師帶我去去實測了學校金杯海獅車的內部尺寸做為參考，祝二位老師在以后的生活跟工作中事事順利，百尺竿頭更進一步。參考文獻[1] :機械工業(yè)出版社,19
