VPS Implicit - Dynamics (Modal Analysis and NVH)

Learn how to set up a modal and frequency response model. Learn about typical NVH results and how to obtain and evaluate them.
CAE engineers with a focus on NVH and comfort.

In this course, the participants will be introduced to linear structural dynamics and working with the NVH application integrated with VPS. Harmonic analyses and their structure will be discussed. Furthermore, the result analysis for NHV simulations is a focus of this course.
