Energy Dissipation and Vibration Control: Modeling, Algorithm, and Devices

The topic of vibration control and energy dissipation is among the oldest and most relevant in the field of engineering. This area encompasses exciting frontier problems ranging from the control of vibrations of drill bits buried thousands of feet underground, to the isolation of towering skyscrapers against seismic excitation, and finally to the stabilization of solar panels attached to a spacecraft. Armed with an ever increasing arsenal of sensing and actuation technologies and theoretical progress, a vibrant community of researchers have gathered to tackle some of the world’s toughest challenges in vibration control and energy suppression problems.

While this issue is not all-inclusive due to the extreme breadth and depth of the field, this issue does showcase some of the state-of-the-art in vibration control and energy dissipation. Specifically, topics in this issue cover: “Evaluation of a Simplified Method to Estimate the Peak Inter-Story Drift Ratio of Steel Frames with Hysteretic Dampers” [1], “PTMD Control on a Benchmark TV Tower under Earthquake and Wind Load Excitations” [2], “Experimental Investigation of a Base Isolation System Incorporating MR Dampers with the High-Order Single Step Control Algorithm” [3], “Integrated Design of Hybrid Interstory-Interbuilding Multi-Actuation Schemes for Vibration Control of Adjacent Buildings under Seismic Excitations” [4], “Active Vibration Suppression of a Motor-Driven Piezoelectric Smart Structure Using Adaptive Fuzzy Sliding Mode Control and Repetitive Control” [5], “Dynamic Response of a Simplified Turbine Blade Model with Under-Platform Dry Friction Dampers Considering Normal Load Variation” [6], “Preliminary Study on the Damping Effect of a Lateral Damping Buffer under a Debris Flow Load” [7], “Self-Tuning Fuzzy Control for Seismic Protection of Smart Base-Isolated Buildings Subjected to Pulse-Type Near-Fault Earthquakes” [8], “The Bivariate Empirical Mode Decomposition and Its Contribution to Grinding Chatter Detection” [9], “Optimization Design of Coupling Beam Metal Damper in Shear Wall Structures” [10], “Wind Turbine Gearbox Fault Diagnosis Based on Improved EEMD and Hilbert Square Demodulation” [11], “Investigations on the Effects of Vortex-Induced Vibration with Different Distributions of Lorentz Forces” [12], “An Experimental Validated Control Strategy of Maglev Vehicle-Bridge Self-Excited Vibration” [13], and “A Novel Hybrid Semi-Active Mass Damper Configuration for Structural Applications” [14].
