Cambridge Collaborative Inc. presents SEAM

For over 30 years, Cambridge Collaborative’s SEAM® software has provided a method of analysis that is particularly well-suited for studying the dynamic response of complex structures at mid and high frequencies.

SEAM is used to predict interior noise and vibration in automobiles, aircraft, and construction equipment cabs as well as the radiated noise from ships and the vibroacoustic environments for spacecraft. Other applications include machinery noise, industrial noise, and building acoustics.

SEAM includes a complete implementation of statistical energy analysis (SEA). The complex dynamic system being analyzed is divided into a set of substructures and acoustic elements. The modes of each substructure and acoustic element are grouped into SEA subsystems. The flow of energy between the different subsystems is proportional to the modal energies of the subsystems and the coupling factors. The SEAM program calculates all required coupling factors and performs a power balance for each subsystem. The resulting equations are solved for the modal energy and response of each subsystem.

About Cambridge Collaborative

Cambridge Collaborative (CCi) provides a wide range of engineering services, including software, testing, R&D and consulting. These services address general noise and vibration problems as well as statistical energy analysis (SEA) related work. While the engineers and scientists at Cambridge Collaborative are considered to be experts on SEA, CCi is also active in testing and data analysis, product optimization, and product design.
