Накратко на български

Виброакустиката на периодичните структури изследва как повтарящи се модели от материали контролират пътя на вибрациите и звука. Това помага за създаването на по-ефективни шумоизолации и защити от вибрации в широк честотен диапазон.

VIbro-acoustics of PERiodic media

VIPER is a European Joint Doctorate on Vibroacoustics. VIPER aims at consolidating academic research dealing with VIbroacoustics of PERiodic media. The VIPER project’ main goal is to develop and to validate tools for the design of global vibroacoustic treatments based on periodic patterns allowing passive control of vibration and acoustic paths in layered concepts. This will be achieved by addressing in-depth structural periodicity stiffness as well as absorption attributes. The proposed concepts will ensure a significant improvement of vibroacoustic performances in a wide frequency range. Dealing with large scale periodic structural-acoustic concepts involves a multi-scale aspect that needs specific numerical tools. The VIPER project main objectives can be summarized as follows: 1 - Addressing most of the theoretical and numerical modelling issues connected to the multi-scale characteristics of the vibroacoustics in periodic media. 2 - Assessment of the topology of periodic structures effects on the vibroacoustic performances. 3 - Focusing on the meso-scale constitutive materials effects, with the improvement of the core material performance for vibroacoustics applications. 4 - Studying the design, feasibility and manufacturing of the periodic media concepts.

Цел на проекта

VIPER is a European Joint Doctorate network focused on research in VIbroacoustic of PERiodic media. Structural periodic design is a powerful strategy for lightweight structures achievements while remaining a convenient solution for manufacturing aspects. One of the research targets is the inclusion of vibroacoustic design rules at early stage of products development through the use of periodic media which exhibit proper dynamic filtering effects. In order to understand how periodic concepts can improve the broadband vibroacoustic signatures and performances, the VIPER project will develop and validate tools for the design of global vibroacoustic treatments based on periodic patterns allowing passive control of structural and acoustical paths in layered concepts. Dealing with large scale periodic structural-acoustic concepts involves a multi-scale aspect that needs specific numerical tools. A two scale strategy will be pursued to handle periodicity effects: the meso-scale, related to the cell or the span size, and the macro-scale related to the final structure size. Bridging the cell scale behavior and the vibroacoustic indicators is a challenging issue which will dramatically improve the macro structural design.As the cell topology and constitutive materials are important data, VIPER will consider the combination of different materials and structural arrangements, in which viscoelastic, poroelastic, auxetic materials will play a major role. Finally, this project will also address the lack of perfect periodicity which can be considered both in view of robustness and design analysis of proposed periodicity based concepts. VIPER has a multi-disciplinary character, coupling expertise from material science, vibration and acoustics as well as applied mathematics. It can offer different applications in transports (aeronautics and space, automobile), energy and civil engineering sectors, where vibroacoustic integrity and comfort can be crucial points.
