چکیده
Analytical and numerical simulations are carried out in order to identify physical parameters affecting acoustic and motion control by viscoelastic piezo-electric and material damping. Numerical simulations in terms of critical parameters, such as relaxation functions of the structure and piezo-electric devices, aerodynamic coefficients, Mach number, are carried out to evaluate their sensitivity to system responses, sensing and structural control.

Bending of Viscoelastic Beams under Piezoelectric Control – Analytical and Massively Parallel Computational Simulations
2. INTRODUCTION Piezoelectric effects are of increasing importance in the control and sensing of structural element deflections. Elastic piezoelectric theory has been extensively developed (Leibowitz & Vinson 1993). Hilton et al. (1997) have presented an extended bibliography and discussed past contributions as well as formulated an analytical nonlinear theory of anisotropic piezoelectric-therm...

Additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. In this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...
متن کاملCharacterizing the viscoelastic stiffness and damping of ferroelectrics during electric field cycling: experiments and modeling
Motivated by a desire to engineer stiff materials (e.g., ceramics) to also have high energy dissipation, the viscoelastic stiffness and damping in ferroelectric ceramics subjected to electric fi elds higher than the coercive fi eld is investigated. Indeed, dynamic excitations of ferroelectrics occur in many of their applications, e.g., in sensors and actuators; thus, there is interest in studyi...

متن کاملVehicle Cabin Noise Simulation due to High-frequencies Stimulation
In this paper, the acoustic environment in a vehicle cabin under the influence of highfrequencies aerodynamic sources has been studied. Some panels on the windshield, the roof, the doors, the front pillars, and the floor of a vehicle simulated as input source of noise when the car is moving at high speed, i.e. 112 km/h. The status of vehicle cabin in each of these modes has been studied and com...
