Vibroacoustic modelling software aids
analysis
AutoSEA2 is a statistical energy analysis (SEA) based simulation software that addresses the higher frequency vibration and acoustic response of systems.
Part of ESI Group's comprehensive suite of virtual prototyping solutions, AutoSEA2 is a statistical energy analysis (SEA) based simulation software that addresses the higher frequency vibration and acoustic response of systems The 2004 version includes significant new capabilities such as advanced SEA model building capabilities from CAD and finite element models, new load-case management functionality, an innovative sound package modeller, and advanced predictive tools
"AutoSEA2 was developed around one simple key concept: increase modelling productivity for the many customers who tackle very complex problems and have little time on their hands", says Benjamin Cimerman, Vibro Acoustic Product Manager, ESI Group.
"We have learned a lot from our clients and I am confident that we have done a very good job at bringing many of the user requirements and suggestions to life in this new version".
AutoSEA2 2004's new model building and management features allow element-based creation of subsystems from finite elements or CAD models.
This functionality significantly reduces the amount of node-picking required to create subsystems and therefore speeds-up the model-building process, helping engineers to create more realistic-looking models - a first step on the road to semi-automatic model building.
The load-case management feature allows engineers to shift quickly and without the risk of error through various operating conditions.
It is a key feature in making AutoSEA2 more robust for product design environments.
The new sound package management module is specifically designed for the automotive industry.
It allows OEMs and suppliers to compare performance between two or more full-vehicle sound packages with the click of a button, thus dramatically enhancing the value of AutoSEA2 modelling in sound package design.
AutoSEA2's scientific and analysis capabilities are enhanced thanks to a ground-breaking variance prediction module as well as numerous others enhancements such as subdivision of panels, interior point junctions, etc.
The new variance prediction model sheds an entirely new light on statistical modelling.
It was developed in response to requirements emanating from the aerospace industry but it will be a powerful tool for all users who want to quantify the confidence that can be applied to simulation results.
Virtual prototyping solutions reduce reliance on costly and time-consuming physical testing, speed up the product development process, and optimise the use of noise and vibration control materials.
ESI Group's vibroacoustic software portfolio includes AutoSEA2; Nova, a software package dedicated to the design of layered acoustic components, Foam-X, a data acquisition and processing software for identifying the acoustic properties of poroelastic materials from impedance tube measurements for both SEA high frequency analysis and low frequency analysis as can be simulated by Rayon.
Using both finite element methods and boundary element methods, Rayon is a low-frequency simulation software package for the prediction of the acoustic performance of untrimmed and trimmed structures.
