چکیده

The article is devoted to the dependency analysis of the thermoacoustic devices performance from acoustic wave parameters (frequency, pressure magnitude etc.). Detailed study of electroacoustic parameters impact on the overall productivity of loudspeaker driven thermoacoustic systems is given. Authors proposed the structure and algorithm basis of the microprocessor system for automated electroacoustic performance calculation. Proposed by Fusco et al. [1] two sensor method is implemented in digital signal processing algorithm for real-time acoustic power calculation. Synthesized microprocessor system is tested during the experimental research of the loudspeaker driven standing wave thermoacoustic refrigerator performance measurements. Analysis of the results obtained shows that the proposed microprocessor system with implemented data processing algorithm can be used for calculations of the thermoacoustic devices overall efficiency.

Analytical Approach for Vibration Analysis of a Microsensor with Two layers of Silicon and Piezoelectric based on MCST

The vibration analysis is an important step in the design and optimization of microsensors. In most of the cases, COMSOL software is employed to consider the size-dependency on the dynamic behavior in the MEMS sensors. In this paper, the Modified Couple Stress Theory (MCST) is used to capture the size effect on dynamic behavior in a microsensor with two layers of the silicon and piezoelectric. ...
