Simulated NVH testing you can see and hear.
Visualization of the noise pressure level
outside the gearbox and vibration-
induced von Mises stress in its housing.
The most effective approach for reducing the noise radiation
from a gearbox is to perform a vibroacoustic analysis to
learn how the design can be improved. Noise, vibration, and
harshness (NVH) testing is an important part of the design
process, and it can be simulated with multiphysics software.
The COMSOL Multiphysics® software is used for simulating
designs, devices, and processes in all fields of engineering,
manufacturing, and scientific research. See how you can apply
it to modeling gearbox vibration and noise.
