Python toolbox for vibroacoustics

This toolbox is the code extension for the book A. Peiffer: Vibroacoustic Simulation: In Introduction to Statistical Energy Analysis and Hybrid Methods, John Wiley, 2022

Wiley book details

Order book

This toolbox allows the reader to follow the examples in the book. People that are interested in vibroacoustic simulation with a focus on statistical energy analysis (SEA) and hybrid methods (hybrid FEM/SEA), to perform SEA simulation without heavy licence costs.

Contributing to pyva

The current version is the baseline for further extensions. It was mainly driven by providing examples and test cases for the book on Vibroacoustic Simulation. Contributions are highly welcome. The following extensions shall be included mid-term

A major step is a GUI development! Here, suggestions would be very helpful. I am currently thinking about a combination of pyqt and vtk, eventually integrating cadquery, opencascade, gmesh or any other option to handle geometry and meshes. However, I am still scanning the options.

Main Module

• Engineering units contraints, e.g. setting pressure or velocity level of one SEA subsystem

Coupling Package

• point junctions
• inclusion of beams in line junctions

Properties Package

Geometrical Property Module

• Further Beam Cross Sections
