[ 1 ] - Identification of Nonlinear Modal Interactions in a Beam-Mass-Spring-Damper System based on Mono-Frequency Vibration Response

In this paper, nonlinear modal interactions caused by one-to-three internal resonance in a beam-mass-spring-damper system are investigated based on nonlinear system identification. For this purpose, the equations governing the transverse vibrations of the beam and mass are analyzed via the multiple scale method and the vibration response of the system under primary resonance is extracted. Then,...

[ 2 ] - Aeolian Vibrations of Transmission Line Conductors with More than One Damper

To reduce the damages of aeolian vibration of conductors to the power transmission networks, the most common method is installation of Stock-bridge dampers. Estimation of the damper’s dissipated energy is an important factor in determining the number and location of installation of these types of vibration absorbers. This estimation is strongly dependent upon the assumed mode shape of the condu...
