Optimization and improvement of WHOOSE noise in intake system of a certain PK vehicle model
WHOOSE noise in the intake system is one of the common noises in turbocharged engines.In order to avoid customer complaints and effectively improve the user's driving experience,a series of research work has been carried out on the intake system.Grooves were made on the inner wall of the vortex shell,high-frequency silencers were added inside the air filter,wall thickness of the intercooling inlet pipe was increased,and a guide cover was added to the air filter outlet pipe.The effectiveness of the plan was verified through CAE analysis and NVH testing.The experimental results indicated that the implemented optimization scheme can effectively reduce the WHOOSE noise level of the intake system,which has certain guiding significance for the research of related NVH problems.
