ZHAOHongfei1，LI Chunnan2，WEI Ning3，ZHANGHongxian1，CHENYue1 （1.Liuzhou KeyLaboratoryofTestand Control Intellgence，Liuzhou Instituteof Technology，Liuzhou 545616，China; 2.Liuzhou Kaikey Technology Co.，Ltd.，Liuzhou 545616，China； 3.SchlofutomotieadIfoationEngeringGuangxiEcoEngineingVocatioal&TecicalClge，Lzhou5450in） Abstract：Thispaperdiagnoses，analyesandcontrolsthewhistling noiseoccuringduringacelerationandcoastingofavehicle. The problemconditionis determinedbysubjectiveevaluation.The actual vehicle testing show that thereare whistling points in the car above 3600r/min . The correlation analysis shows that the whistling is caused by the deformation of the generator claw tip atached tothefrontendoftheengine.Byoptimizing theintegermodulusstructure，thewhistlingproblemisefectively controlled，which ensures product consistency and upgrades vehicle sound quality.
