Structure Borne Noise

Structure Borne Noise Vibration Simulation with
Hybrid Models
As the development cycle of a new vehicle model
shortens, CAE techniques become increasingly
important in the early design stages. Traditional
CAE analysis of vehicle requires a large scale FE
model resulting in longer model development and
computational times. Hybrid modeling method,
however, can handle a mixture of pure analysis
design models and experimentally obtained dynamic
characteristics, thus reducing the development
lead time.
Needs

• To study the Vehicle Interior Noise Prediction
  Method Using the Hybrid Model.
• Optimal Design Guidance will be supplied to
  Improve the Booming Noise.
• To Accomplish Systematic Simulation Procedure for
  the Structure Borne Noise Analysis and
  Improvement including Vibro-Acoustic, Transfer
  Path Analysis.

Goals
Technical Aspect
