N.V.H Analysis of a Vehicle using Statistical Energy Analysis
Blekinge Institute of Technology, Faculty of Engineering, Department of Mechanical Engineering.
2014 (English)Student thesis
Abstract [en]

Modern vehicle development heavily requires noise and vibration refinement to deliver the proper level of customer satisfaction and methods are improved daily. Statistical Energy Analysis (SEA) presented in 70’s and in the recent decade it has been highly applied in the automotive industry and different commercial software have been introduced. LeanNova Engineering Co. has decided to study the method and apply it in the design and engineering services. In this thesis the concept of the method was studied. Some simple examples were solved (by using MATLAB and FEM software), and the results were compared to a SEA commercial software named VA One results. Measurement related to acoustic properties of Porous Material (in order to use as input in the VA One software) by Impedance Tube and based on a method presented by University of Sherbrooke and software of FOAMX have been done. Finally a whole car body model was generated and the effect of sound pressure as an input at different locations of body was evaluated.
