AutoSEA2: A New Design Evaluation Tool for Noise and Vibration Engineering

This paper describes the development of the AutoSEA2 statistical energy analysis (SEA) code. The development includes a family of quasi-conformal 3D subsystems; an automatic subsystem connection scheme and implementation of full wave transmission theory for more robust and accurate modeling of junctions. The application of these innovations to the modeling of automobile interior noise demonstrates the potential for this evolution of SEA to define a new “design evaluation” process which is an attractive alternative to finite element methods at the design stage.
