Automotive N.V.H Development & Examples of C.A.E Application

자동차의 소음진동 성능개발 및 CAE 적용 사례

This paper describes the examples of Noise, Vibration and Harshness(N.V.H) development applying Computer Aided Engineering(CAE). Some Commercial Software was used to reduce the cost, development time and to predict the Noise and vibration phenomenon of new vehicle design. This paper is including measured and analysis data, and tried to prove the good correlation between measured and calculated data, so test and analysis data were compared seriously and carefully. Analysis models, which were used to predict and develop the NVH phenomenon, analysis method, and a field of --0application are explained briefly. Also, model pictures are presenting in this paper. This paper describes the analyzing method of the calculated results, design modification and development procedure, and NVH performance target setting up and procedure.
