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.
