Abstract
Calibration of the linear element of piezoceramic pressure transducers in the blasting chamber by a drop weight method
Incoming article date: 11.12.2014The article focuses on the brief analysis of existing measuring devices of parameters of shock-wave processes include, in particular, electrical discharge in condensed medium. Conversion coefficients for calculation of amplitude of pressure of a shock-acoustic wave were found by means of mathematical modeling of the physical process happening in the piezoceramic pressure transducer when pulse mechanical loading influences on it on the assumption of absolute sharp border. The results of the calibration of the linear module of piezoceramic pressure transducers in the transmission condensed medium in the blasting chamber using a drop weight method are described.
