PIPECALC1 - Evaluation of numerical models for calculations of the acoustic behavior of plastic pipes

Project: Research project

Description

Numerical analyzes, such as the finite element method approach, can be used for future development of innovative products as well as for the optimization of existing systems. Those models shall reflect reality in a sufficiently precise manner. This requires suitable material and structure models, input parameters and analysis methods. The aim of the investigations is to find the best fitting configuration of a FEM calculation ambiance and to evaluate several materials and pipe structures. For this purpose several plastic sheets will be investigated by structure borne and airborne sound measurements in the laboratory. Operative works are inter alia experimental modal analysis, sound intensity measurements and airborne sound reduction measurements to evaluate the transmission loss, radiation factor and other parameters. This enables to determine the vibration behavior and sound radiation of the test bodies as a basis for the FEM Model. Final aim is to find measures to reduce noise emission for future pipe devellopment.
