Abstract In order to demonstrate the relevance of considering Vortex-Induced Vibrations (VIV) in structural design marine structures, this study proposes an alternative experimental and analytical approach wet conditions measure fluid–structure interaction near field quantify viscous damping with measured 3D hydrodynamic accelerations. It was demonstrated that VIV caused incremented 5.00% coeff...

The aim of this paper is to study the dynamic characteristics of micromechanical rectangular plates used as sensing elements in a viscous compressible fluid. A novel modelling procedure for the plate-fluid interaction problem is developed on the basis of linearized Navier-Stokes equations and no-slip conditions. Analytical expression for the fluid-loading impedance is obtained using a double Fo...

A method is suggested to reduce structural response to earthquakes using viscous dampers with their effect magnified by mechanical levers (lever arms). The lever arms are used to magnify the drift and the drift velocities transferred from the structure to the dampers thus producing in larger energy dissipation. An optimal design procedure based on the LQR technique is proposed in this study to ...

In single stage valves, the main spools are stroked directly by solenoid actuators. They are cheaper and more reliable than multistage valves. Their use, however, is restricted to low bandwidth and low flow rate applications due to the limitation of the solenoid actuators. Our research focuses on alleviating the need for large solenoids in single stage valves by advantageously using fluid flow ...

We propose the use of electrostatic force feedback to control the stiffness, damping, or mass of MEMS. If feedback forces are proportional to sensed displacement, velocity, or acceleration of a MEMS proo...
