研究目的
To address the problem of determining the resonance frequency of ultrasonic vibrating systems (radiators) in 'Bulava' type apparatuses for efficient operation.
研究成果
The experiments show that it is possible to determine the resonant frequency of ultrasonic vibrating systems during operation, with the maximum speed of change in inductance L serving as a reliable tuning criterion. This allows for periodic automatic or manual frequency control in 'Bulava' apparatuses, matching resonance frequencies measured in water under pre-cavitation conditions.
研究不足
The system is limited by shifts in resonance frequencies during operation, which reduce efficiency, and the inability to use traditional automatic frequency control systems due to masking of mechanical resonance by electric resonance. Additionally, cavitation generation at higher voltages complicates impedance changes.
1：Experimental Design and Method Selection:
The study involves analyzing the matching of ultrasonic vibrating systems with generators in 'Bulava' apparatuses, focusing on maintaining balance between mechanical resonance of the system and electric resonance of the matching LC-contour.
2：Sample Selection and Data Sources:
Ultrasonic vibrating systems from 'Bulava' apparatuses are used, with data collected through frequency tuning and measurements of current, voltage, and impedance.
3：List of Experimental Equipment and Materials:
Includes electronic generators, transformers, reconfigurable L elements (ferromagnetic variometers), piezoelectric elements, and control systems.
4：Experimental Procedures and Operational Workflow:
Frequency characteristics are obtained by varying the frequency of the ultrasonic vibrating system and adjusting the inductance L to maintain resonance mode, with measurements of amplitude-frequency characteristics for current, voltage, and impedance.
5：Data Analysis Methods:
Analysis involves interpreting amplitude-frequency characteristics and impedance changes to identify resonance frequencies and system behavior.
