Experimental and computational evaluation of modal identification techniques for structural damping estimation [PDF]
E3S Web of Conferences, 2022 The damping ratio is a key indicator of a structures susceptability to human discomfort due to dynamic loads. Computational models, wind tunnel studies and empirical data can provide estimates of the damping ratio of a structure.

International Journal of Naval Architecture and Ocean Engineering, 2022 The hydrodynamic damping characteristics of elastic rotating propeller blades are investigated theoretically and experimentally. Firstly, the modal hydrodynamic damping ratio of propeller blade rotating in water is theoretically predicted based on the ...

Structural Control & Health Monitoring, 2022 For design of tuned mass‐damper‐inerter (TMDI) in flexible multi‐degrees‐of‐freedom (MDOF) structures, the classic 2‐DOF model is incapable of accounting for the background flexibility that comes from non‐resonant modes, leading to an unbalance in the ...

The Determination of Modal Damping Ratios and Natural Frequencies from Bispectrum Modeling [PDF]
OCEANS '87, 1987 We present a new signal processing and testing technique by using a higher statistical moment, the bispectrum, to determine the damping ratio and natural frequency of offshore structures excited by both unexpected Gaussian forces and known non-Gaussian driving forces. Due to unexpected exciting forces, such as turbulence, in the ocean, environment, the

Optimization of VEDs for Vibration Control of Transmission Line Tower
Advances in Civil Engineering, 2021 This paper investigates the optimization of viscoelastic dampers (VEDs) for vibration control of a transmission line tower. Considering the stiffness of the steel brace connected to a VED, the mechanical model of the VED-brace system was established ...
