A modular bearing with internal piezoshunt damping
When a piezoelectric transducer is incorporated in a mechanical structure, it is possible to damp the structural vibrations of the base structure by passive energy dissipation in the electrical domain [1]. Due to the strong electromechanical coupling in piezoelectric elements, the mechanical energy can be efficiently converted to electrical energy. By shunting the piezoelectric element to a pas...
متن کاملParameter Identification in a Generalized Time-Harmonic Rayleigh Damping Model for Elastography
The identifiability of the two damping components of a Generalized Rayleigh Damping model is investigated through analysis of the continuum equilibrium equations as well as a simple spring-mass system. Generalized Rayleigh Damping provides a more diversified attenuation model than pure Viscoelasticity, with two parameters to describe attenuation effects and account for the complex damping behav...
متن کاملPrecision Identification of Nonlinear Damping Parameter for a Miniature Moving-Coil Transducer
The nonlinear damping behavior is usually ignored in the design of a miniature moving-coil loudspeaker. But when the loudspeaker operated in air, the damping parameter varies with the voice-coil displacement corresponding due to viscous air flow. The present paper presents an identification model as inverse problem to identify the nonlinear damping parameter in the lumped parameter model for th...
متن کاملIdentification of Dynamic Damping Properties of a Flexible Structural Adhesive
In this paper dynamic damping properties of a nominated flexible structural adhesive have been identified using an extended-direct modal based joint identification method. It has been revealed that damping characteristics of adhesive are correlated to both frequency and mode shape. Young’s and shear moduli increase with frequency but damping on the other hand, decrease. The results showed that ...
متن کاملInternal Report: Parameter Identification and Dynamic Model of MABEL
This research identifies an eleven degree of freedom dynamic model of MABEL, a new robot for the study of bipedal walking and running. Model parameters are identified on the basis of fourteen angles measured by encoders and the commanded torque of the robot’s four independent actuators. The identification process is modular and begins with the cable-driven transmission mechanism of the robot. B...
