✦ Synopsis
The power flow analysis for a floating raft isolation system consisting of constrained damped beams is completed by using the Green function, an analytical method instead of the traditional mobility approach. The transmitted power flow from a harmonic force excitation to the foundation beams via an isolator-raft beam-isolator system is calculated. Some important structural parameters that influence the transmitted power flow are discussed. The conclusions provide a theoretical basis for vibration control in engineering.
