Passive Vibration Control for Fatigue Damage Mitigation in Steel Jacket Platforms

Considering the stress cycles in the joints and members due to wave induced forces on offshore platforms, fatigue analysis is therefore one of the most important analyses in the offshore platforms design. Although most of the steel jacket type platforms are designed and located in areas with relatively high ratios of operational sea-states, for maximum environmental events, would have acceptabl...

Passive vibration control: a structure-immittance approach.

Linear passive vibration absorbers, such as tuned mass dampers, often contain springs, dampers and masses, although recently there has been a growing trend to employ or supplement the mass elements with inerters. When considering possible configurations with these elements broadly, two approaches are normally used: one structure-based and one immittance-based. Both approaches have their advanta...

Genetic Algorithm Based Design Of Passive Elements For Vibration Control

An Advanced System for Vibration Control of Flexible Structures

The objective of the research work here presented is the rejection of a broadband disturbance in a vibrating flexible structure. From a technological point of view, the problem is tackled using an advanced lightweight magnetostrictive resonant actuator with an integrated optical strain sensor. The adopted control strategy consists of a two-levels controller. Usefully exploiting the measurement ...
