basic information
<< Ultrasonic Sound Pressure Measurement and Analysis >> 1) Regarding time series data, we will analyze and evaluate the statistical properties of the measurement data (stability and changes of ultrasound) through feedback analysis using a multivariate autoregressive model. 2) The effects of the oscillation part due to ultrasonic oscillation will be analyzed and evaluated in relation to the surface condition of the target object through impulse response characteristics and autocorrelation analysis as the response characteristics of the ultrasonic vibration phenomenon. 3) The interaction between the oscillation and the target object (cleaning items, cleaning solution, water tank, etc.) will be evaluated through the analysis of power contribution rates. 4) Concerning the use of ultrasound (cleaning, processing, stirring, etc.), we will analyze and evaluate the dynamic characteristics of ultrasound based on the nonlinear phenomena (results of bispectral analysis) of the target object (propagation of surface elastic waves) or the ultrasound propagating in the target liquid, which are the main factors of the ultrasonic effect. This analytical method is realized based on past experiences and achievements by adapting the complex dynamic characteristics of ultrasonic vibrations to the analysis techniques of time series data for ultrasonic measurement data.
