Dilatant-Fluid Torsional Vibration Damper for a Four-Stroke Diesel Engine Crankshaft
Polish Maritime Research, 2023 This paper presents a study of a viscous torsional vibration damper for a crankshaft of a four-stroke diesel engine. The reliable operation of a widely used silicone-type viscous damper depends on the ability of the silicone oil to absorb the energy of ...

Monitoring of Liquid Viscosity for Viscous Dampers through a Wireless Impedance Measurement System
Applied Sciences, 2021 Viscous dampers are a type of seismic damping equipment widely used in high-rise buildings and bridges. However, the viscosity of the damping fluid inside the viscous damper will change over time during its use, which significantly reduces the seismic ...

Solutions for the Design and Increasing of Efficiency of Viscous Dampers [PDF]
The Open Construction and Building Technology Journal, 2016 In last decades many strategies for seismic vulnerability mitigation of structures have been studied and experimented; in particular energy dissipation by external devices assumes a great importance for the relative simplicity and efficacy. Among all possible approaches the use of fluid viscous dampers are very interesting, because of their velocity ...

Fail‐safe optimization of viscous dampers for seismic retrofitting [PDF]
Earthquake Engineering & Structural Dynamics, 2020 SummaryThis paper presents a new optimization approach for designing minimum‐cost fail‐safe distributions of fluid viscous dampers for seismic retrofitting. Failure is modeled as either complete damage of the dampers or partial degradation of the dampers' properties. In general, this leads to optimization problems with large number of constraints. This
