Introduction Windtunneltestingisacrucialtoolforthedesignanddevelopmentofvariousengineeringproductsandsystems,includingaircraft,automobiles,andbuildingstructures.Theaccuracyandreliabilityofthetestresultsdependonthequalityofthemeasurementandcontrolsystemusedinthewindtunnel.However,traditionalmeasurementandcontrolsystemsareoftenexpensiveandinflexible,makingitchallengingtoadapttovarioustestingscenariosandexperimentalconditions. ThePXIbusplatformprovidesaflexibleandmodularapproachtosystemdesign,makingitanidealchoiceforresearchanddevelopmentprojectsthatrequirehighperformance,scalability,andcustomization.ThisprojectfocusesonthedesignanddevelopmentofawindtunnelmeasurementandcontrolsystembasedonthePXIplatform. Projectobjectives Theprimaryobjectiveofthisprojectistodesignanddevelopacost-effectiveandhigh-performancemeasurementandcontrolsystemforwindtunneltesting.Thesystemshouldbemodular,scalable,andflexible,allowingittoadapttovarioustestingscenariosandexperimentalconditions. Systemrequirements ThewindtunnelmeasurementandcontrolsystembasedonthePXIplatformshouldsatisfythefollowingrequirements: 1.Supportformultiplesensorsandinput/outputchannels. 2.High-speeddataacquisitionandreal-timeprocessingcapability. 3.Modularandflexiblearchitectureforeasysystemexpansionandcustomization. 4.User-friendlysoftwareinterfaceforsystemconfiguration,testsetup,anddatavisualization. 5.Reliableandrobustperformanceunderdifferenttestingconditions.
