Study Of Electric Vehicle's Shape Design

A1ong wth traditionaI fuel automobiIe is continuously increasing, it brings moreand more serious pollution to the earth.Therefore,in the end of twenty century,itcomes fOrth a upsurge to research and manufacture Electric Vehicle (EV) all over theworld. Chinese government has already brought EV into the fateful science andteclinology research item of state's the ninth five year plan and its aim is to develop aimpoYtant industry. Consequently, the writer think it is very necessary to the researchof EV's Industrial Design while we study key technique.The current design of EV has two kinds of methods,the refit design and the all newdesign. The EV'design in our country is almost the refit design, but it can notembodies the advantage of EV. Dlle to EV have not enormous gas engine andcomplicated gearing, then its shape breaks the style of traditional fuel automobiles andfOrms its pafticular sty1e, outstanding the characteristic of streamline, miniaturizationand light-duty. So the thesis is mostly to study the all new design of EV and strivehard to make EV's lndustrial Design match beautiful shape, human engineering,aerodynamics and principle of the green design.The thesis analyzes the main factors that influencee EV's continuously chargemileage.according to the importance of different factor and the influencee of differentshape design that affact a factor, the thesis study the design of EV and make it canincrease continuous1y charge mi1eage whi1e it satisfy beautifu1 shape and humanengineering.with regard to EV's beautiful shaPe, the thesis analyzed the principle to attainbeautiful shape and visual illusion in automobile design. Because most of EV's bodyis too short a little, the thesis emphasize how to attain a subective ideal shaPe throughthe principle to attain beautiful shaPe and the visual illusion;On human engineering,the thesis aim mainly at the analyse of fist-ellipse, fOot-ellipse and at the design ofmetef, seat and lamp in order to improve driver's efficiency at the most. At the sametime,by the way of analyzing passengers in electric buses and electric cars on humanengineering, it acquire the size of eIect fic buses and elect fic cars' room,1n order tolIattain aerodynamicist's EV shape, the thesis cite conclusion from recent paper ,then summarize optimum value by synthesizing manufacturing technology and human engineering .finally the writer make use of the above research result and adopt latest NURBS mold method of software of 3DS MAX to design EV's conception drawing .
