Dynamics / NVH

Damped and undamped vibration analysis is performed to identify the dynamic characteristics of the structure. These analyses are the centre of NVH-engineering (Noise, Vibration, Harshness), which can determine the performance of the structures' vibration and acoustic transmission. The structure is connected to an acoustic cavity model via the Boundary Element Method (BEM) for calculating the emitted acoustic pressures.

Application range (Extract):

Frequency Response analysis

Acoustics

• Sound propagation in internal spaces
• Consideration of the influence of forces occurring at the engine support's and/or suspension sub frame's attachment points
  
• Consideration of the influence of other sound sources like engines, road loads, etc.
