Energy Finite Element Method (EFEM) and Statistical Energy Analysis (SEA) of a Heavy Equipment Cab 1999-01-1705
The energy finite element method (EFEM) was developed to utilize available finite element geometric models for high frequency structural-acoustic analysis. Statistical Energy Analysis (SEA) is a lumped parameter approach currently in widespread use for high frequency analysis. In this investigation, EFEM and SEA models were developed for components of a heavy equipment cab. A generalized joint process (GJP) was developed and used for processing the various joints between structural subsystems. The structural predictions were compared to each other as well as to measurements.
