Noise, vibration, and harshness (NVH) is the study and measurement of auditory and tactile feedback in an object. For many products, these quantities are very important for the customer experience. Since sounds can be both an annoyance and a benefit, NVH analysis helps identify where a sound is coming from and why. Engineers can then reduce or eliminate unwanted noises, as well as enhance beneficial sounds.
NVH Analysis is often performed using a frequency domain approach. There are many possibilities for performing NVH Analysis using Ansys LS-DYNA software.
Here, a set of examples for vibrational, acoustic and fatigue analysis are presented.
