Acoustic comfort of vehicles: characterization of vibration sources
Presented by :Serge Puvilland, Institut Carnot ESP
Date:July 4, 2019 at 11:00 a.m.
Duration :45 minutes + questions

It is generally accepted that the characterization of vehicle vibration sources is essential to achieve a good level of acoustic performance. How to proceed? By trying to predict and minimize vibrations and the contribution of structure-borne noise. Today, car manufacturers have integrated numerical methodologies allowing a complete characterization of active components (vibration sources) and passive components (body). However, these solutions are complex and costly.

This webinar presents a simplified methodology, more economical, through the realization of a hybrid test/calculation model. The objective is to link simple models and thus optimize the design of components, decoupling blocks and the host structure in relation to the vibration and acoustic performance.

Program of the presentation :

1. Background

2. Simplified method: hybrid test/calculation model

3. Application to a motorised seat

This webinar is organized in partnership with :
