Abstract
From the article of Analyze on a coupled beam vibration system by FEM (I): theory, equation of motion of the beam system with attachments is established by conventional finite element method, and some parameters, such as natural frequencies, associated mode shapes, are obtained. The mode localization and frequency loci veering phenomena of a weakly coupled beam system with multiple spring-mass systems are investigated. Studies show that for weakly coupled beam system with attachments, the mode localization and loci veering will occur once there is a disorder in the system.
