Experimental investigation on using the piezoelectric and electromagnetic vibration absorbers in milling

Sweeping piezoelectric patch vibration absorbers

This paper presents a simulation study concerning the low-mid frequencies control of flexural vibration in a lightly damped thin plate, equipped with five time-varying shunted vibration absorbers. The panel is excited by a rain-on-the-roof broad frequency band stationary disturbance. The absorbers are composed of piezoelectric patches connected to time-varying RL shunt circuits. Continuous, swe...

Experimental Investigation of Active Vibration Control Using a Filtered-Error Neural Network and Piezoelectric Actuators

Parametric Analysis and Experimental Verification of a Hybrid Vibration Energy Harvester Combining Piezoelectric and Electromagnetic Mechanisms

Considering coil inductance and the spatial distribution of the magnetic field, this paper developed an approximate distributed-parameter model of a hybrid energy harvester (HEH). The analytical solutions were compared with numerical solutions. The effects of load resistances, electromechanical coupling factors, mechanical damping ratio, coil parameters and size scale on performance were invest...

Experimental investigation of the gyroscopic and rotary inertia effects on the chatter boundary in a milling process

Experimental examination of the gyroscopic and rotary inertia effects on the chatter boundary in a milling operation is the chief aim of this article. The equations of motion of the tool vibration are derived based on Timoshenko beam theory and Hamilton principle by considering gyroscopic moment, rotary inertia, velocity-dependent process damping and radial immersion effect. For a range of dept...
