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.
