Dynamic and vibroacoustic response of timber floor panels. Measurements and non-linear numerical simulations

Résumé

The present work concerns the dynamic and vibroacoustic response of timber floor panels aswell as the study of the effect of material nonlinearities and damping. Each panel is composedof glued laminated beams and wood constituting the floor. The dimensions of the panels aredefined to ensure appropriate implementation and transport conditions. For these reasons,the width of the panels is fixed at 2.40 m, and the length is 7.2 m. Two types of floor panelswere investigated with and without struts. A numerical approach based on 3D finite elementmethod is used to solve the problem. Our finite element model and the mechanical propertiesof the used materials are first validated from comparisons with experimental tests carried outin statics [1]. A dynamic non-linear analysis of the timber floor panels has been then con-ducted under a walking time history and the vibroacoustic response of the system is finallyinvestigated
