Noise simulation for motor vehicles: Applying statistical methods

In co-operation with the industrial Partner Magna Steyr Fahrzeugtechnik (MSF), the Acoustic Competence Centre ACC Graz has developed a methodology to calculate the most important parameters of a vehicle model based on Statistical Energy Analysis (SEA). To determine these parameters, Finite Element (FE) models of the vehicle parts are used. This Hybrid Method (FEM + SEA) is a pure predictive procedure and can be applied in the vehicle development without any measurement results from tests.
