Simulated NVH testing you can see and hear. Visualization of the noise pressure level outside the gearbox and vibrationinduced 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. comsol.blog/NVH-simulation Free Info at http://info.hotims.com/73006-715http://info.hotims.com/73006-715
