Introduction

Vehicleengineeringisamultidisciplinaryfieldthatencompassesvariousaspectsofautomotivedesignandmanufacturing.Theobjectiveofvehicleengineeringistodesignanddevelopvehiclesthatmeettheperformancerequirementsandsafetystandardswhilealsoensuringoptimalfuelefficiencyandpassengercomfort.Thedevelopmentofnewtechnologies,suchaselectricandautonomousvehicles,hasbroughtaboutsignificantchangesintheindustry,leadingtoagreaterdemandforskilledengineers.

Thispaperaimstodesignahigh-performancevehiclethatcancompeteinthemarketusingadesignapproachbasedontheoreticalanalysisandsimulation.Thefocusisontheselectionofthepowertrain,suspensionsystem,andaerodynamicdesigntomeettheperformancerequirementsofthevehicle.

Designprocess

Thedesignprocessbeginswithidentifyingtheperformancerequirementsofthevehicle,whichincludetopspeed,acceleration,andhandling.Thenextstepisselectingthepowertrain,whichincludestheengine,transmission,anddrivetrain.Thechoiceofpowertrainaffectsthevehicle'sperformance,fuelefficiency,andemissions.Forthisdesign,ahigh-performancegasolineengineandamanualtransmissionwereselected.

Thesuspensionsystemisacriticalcomponentofthevehiclethataffectsthehandlingandridecomfort.Thesuspensiondesignwasbasedonadouble-wishbonefrontandmulti-linkrearsuspensionsystem.Thesuspensioncomponentswereselectedbasedonthevehicle'sweight,performancerequirements,andridecomfort.

Theaerodynamicdesignofthevehiclewasoptimizedusingcomputationalfluiddynamics(CFD)simulation.Thedesignincludedafrontsplitter,reardiffuser,andwingforimproveddownforceandreduceddrag.

Simulationandtesting

Thedesignedvehiclewassubjectedtosimulationandtestingtoevaluateitsperformance.Thesimulationsincludedaerodynamicanalysis,vehicledynamics,andpowertrainperformance.Thevehiclewastestedforacceleration,topspeed,andhandling.Theresultsshowedthatthedesignedvehiclemettheperformancerequirementsandhadacompetitiveedgeinthemarket.
