Summary: This paper proposes and experimentally verifies a two-mass model for the dynamics of structures with embedded particle dampers (EPDs). The model captures the nonlinear effects caused by the sliding motion of particles, and the dynamics of the system transition from linear to nonlinear behavior as the acceleration response amplitude increases. The model is validated through experiments on a beam structure with EPDs, and it successfully reproduces the nonlinear phenomena observed in the beam.

Summary: This study investigates the nonlinear mass and damping effects of nonlinear electromagnetic shunt damping on the vibration isolation performance of a permanent magnets based nonlinear vibration isolator. By designing a specific electromagnetic structure and analyzing the mechanic-electromagnetic coupling coefficient, equivalent nonlinear damping and mass are achieved. The use of inductance is found to change the mass and frequency response of the vibration isolator.

Summary: In this study, a passive vibration control method called translational root mounting method is proposed and investigated for suppressing low frequency vibrations of spacecraft solar panels. The method employs dampers installed at the roots of solar panels to modify the fundamental mode shape of the panel and dissipate the dynamic energy, resulting in effective vibration reduction.

Summary: Different layouts of adaptive tuned mass dampers using shape memory alloys have been proposed. This paper compares wire-based and beam-based layouts in terms of adaptation capability, force exerted, and power consumption. Models are developed for both layouts, minimizing the required inputs related to device geometry, shape memory alloy characteristics, and vibration input. The models are experimentally validated and used for comparing the two layouts.

Summary: This paper investigates the failure of a stay cable on the Saint-Nazaire bridge in detail. Fatigue corrosion is identified as the main cause of wire breakage. The study reveals that the fatigue stress at the anchorages is caused by vibrations induced by vortex detachments. The Stockbridge damper is found to be effective in reducing vibration amplitudes.

Summary: This paper presents a general geometric theory for the in-plane motion of underplatform dampers as a function of blade neck deflection and the resulting platform kinematics. It introduces the concept of equivalent virtual parallel geometry and develops equations for both In-Phase and Out-of-Phase blade vibrations. The paper also proposes a piecewise linear algorithm to pre-compute a cycle and introduces the concept of force Base-Cycle and moment Base-Cycle for the damper-platform system.
