Study on the Resonant Frequency Gliding in the Ultrasonic Systems Loaded with Variable Axial Compression Force

Abstract:

Each component on an industrial ultrasonic system is specifically designed from the very beginning, as part of the resonant system, for each individual application and for a present frequency and with particular working conditions. A series of factors linked to the mechanical system can significantly shift the electrical impedance and the real resonant frequency of the vibrating system. Most frequently, the capability of the ultrasonic generator to solve this problem is limited to a frequency sweeping in the limit of a 1 kHz tracking range around a fixed nominal frequency. When the range of variation exceeds 1 kHz, a more performing, but expensive, generator is needed. The paper presents a set of experiments with variable compression axial force up to 200 daN, specific situation for the ultrasonic activated drilling, and the evolution of the resonant frequency in these conditions in a range up to 3 kHz.
