VA ONE - FE-BEM for Space Structural qualification

Learn to perform acoustic environment qualification for space structures. The course aims at obtaining the vibration response, dynamic stresses, or internal cavities acoustic levels for components, entire payload, or launch vehicle subjected to a launch environment.
Audience
NVH Engineers, Acoustic Test Engineers, etc.
Prerequisites

Basic knowledge of the Finite Element Method (FEM).

概要

This training will be held by our business partner EA Systems Dresden GmbH.
