CAE

n noise and vibration analysis, we employ linear analysis to study the natural frequencies of a system to determine the causes of undesired high-frequency vibrations, fluid-, structure- and air-borne noise or noise transmitted due to modal couplings.

Noise and vibration analysis can be used to:

• suggest various methods to reduce the excitation from the source;
• find resonances in the system and tune it so as not to excite said resonances;
• evaluate the influence, behavior, and contribution of mounts, couplings, isolators, etc. that are employed to reduce the transmission of noise or vibrations;
• understand the dissipation of the noise or vibration energy;
• optimize the properties of acoustic materials such as cabin interior linings, etc.;
• get insights into the loads and deformation of parts and components to prevent fatigue cracking and increase durability.
