Vibration Damping, 2nd Edition: Response Mitigation of Structural and Rotating Systems—Smart, Nonlinear and Hybrid Solutions

Dear Colleagues,

Short Introduction

This Special Issue, “Vibration Damping, 2nd Edition”, in Vibration (MDPI), aims to publish high-quality contributions on vibration damping and dynamic response mitigation in (i) structural/civil systems and (ii) rotating machinery. The Special Issue welcomes passive, semi-passive, active and hybrid strategies, and emphasizes rigorous modelling, identification, optimization and experimental validation. Cross-cutting approaches such as smart materials, shunted electromechanical damping, nonlinear absorbers, periodic/metastructure-inspired designs, and vibration-based energy harvesting are particularly encouraged when they contribute to measurable vibration mitigation.

Aims and Scope

Vibration damping remains critical for safety, reliability, control and performance in both engineering structures and rotating machinery operating under demanding conditions. Recent advances in dissipation mechanisms, smart materials and electromechanical coupling, nonlinear energy transfer, and engineered/periodic structures enable new solutions that combine damping performance, robustness and multifunctionality.

Submissions are especially encouraged within the following two application pillars, supported by a set of cross-cutting methods and technologies.

Pillar 1 — Structural and Civil Vibration Mitigation

Topics include (but are not limited to) the following:

• Damping identification and modelling in structures: modal damping ratios, equivalent damping, amplitude-dependent damping, nonclassical damping;
• Supplemental damping devices and response mitigation strategies: viscous/viscoelastic/friction-based dampers, tuned devices, hybrid solutions;
• Seismic and dynamic performance of structures equipped with energy dissipation systems: performance-based design, validation and case studies;
• Experimental and numerical investigations on real structures and components (panels, frames, floors, bridges, etc.)

Pillar 2 — Rotating Machinery Damping and Industrial Rotordynamics

Topics include (but are not limited to) the following:

• Internal damping mechanisms, stability/instability phenomena, and damping modelling in rotors and rotor–bearing systems;
• Rod-Fastened Rotors (RFRs), nonintegrated heavy-duty turbine rotors and industrial case studies;
• Coupled effects relevant to rotating systems (gyroscopic effects, anisotropy, thermal effects, contact/friction interfaces, supports/foundations);
• Experimental identification/validation in turbomachinery-relevant conditions and practical mitigation solutions.

Cross-cutting Methods and Technologies (supporting both pillars)

Submissions are welcome when they clearly contribute to vibration mitigation in Pillar 1 and/or Pillar 2:

• Damping treatments and dissipative devices: constrained layer damping (CLD), viscoelastic layers, multilayer/sandwich solutions, magnetic and friction-assisted concepts, tuned and hybrid dampers;
• Smart and electromechanical solutions: piezoelectric, magnetostrictive, SMA and MAE-based concepts; shunted and semi-passive electromechanical damping (resistive/resonant/multi-resonant shunts, switching strategies, multimodal shunting, hybrid mechanical–electrical dampers);
• Nonlinear and engineered-structure approaches: nonlinear energy sinks (NES), nonlinear tuned absorbers, vibro-impact and other nonsmooth mechanisms, targeted energy transfer/internal resonances; periodic/metastructure-inspired designs for broadband attenuation and isolation;
• Modelling, optimization and validation: FE and reduced-order/surrogate modelling, nonlinear system identification, experimental modal analysis, uncertainty quantification, robust/multi-objective optimization, proof-of-concept demonstrators, and vibration-based energy harvesting coupled with damping.

Both fundamental and application-oriented papers are welcome, provided they demonstrate clear relevance to vibration damping and include sound modelling/identification and/or experimental validation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Vibration is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
