The leak detection process modeling

The paper describes formalized description concept of the expiration gas process through product manufacturing defects in the control of tightness: Model Internal description based on the use of parameters of circuit theory and mathematical model of the external description made by means of functional expansions obtained on the basis of mathematical models experimental research of the implemented software package external description. A dynamic model of the outflow of gases through product defects is presented by the Wiener-Voltaire equations. The proposed method for studying the outflow of gases through product defects consists a simulation object whose input is subjected to an external action with constant other variable parameters and registration of the output signal. The experimental data are compared with the results of theoretical calculations based on the molecular model of the outflow process.
