Широкосмуговий нановібраційний збуджувач для твердосплавних пластин

Abstract

коливань для твердосплавних різальних пластин WC-Co типорозміру 20×10×5 мм у діапазоні частот від 10 Гц до 3 МГц.

excitation based on the Lorentz force combined with the thermoelastic effect is substantiated, providing vibration generation without conventional mechanical actuators. It has been determined that in the range of 10 kHz to 3 MHz, efficient excitation of bulk elastic waves with amplitudes of 0.1–50 nm is physically achievable. A map of the natural resonance frequencies of the insert was constructed, and rational excitation application points were identified. A laboratory setup architecture with a closed-loop amplitude stabilization system and laser Doppler displacement monitoring is proposed.
