چکیده

In this paper a special kind of aerodynamic system“spoiler” has been designed and tried to show effects ofthis device on braking system of vehicles. Moreover,position of this spoiler has been considered in order tofind optimum point from “safety” and “highest rate ofbraking” point of view for spoiler. The fluent branch ofAnsys software is our main tool to calculate rate offurther force which is produced by spoiler and in thisarticle has been tried to use various figures which showeffects of spoiler at different speeds, angles, and alsoheights. The other major points in this paper are staticpressure of vehicle at different speeds and statues.Undoubtedly, shape of spoiler would be very importantfactor. Thus, in this investigation spoiler has beendesigned and proposed after a lot of simulation fordifferent shapes of spoiler. In the end, there is a veryimportant part as validation since these simulations haveto be validated by experimental way to prove the claims.In this case a special kind of Bmw has been simulatedand results were compared by experimental resultswhich have been presented by Bmw Company. Thedifference between simulation results and experimentalare ignorable and it could be a suitable validation forthis project.
