Method of measuring vibration movements of material points on the surface of the controlled object

摘要

The article outlines the publications on measuring the field of vibration movement of the surface of the controlled object. The authors have conducted the modelling of the trace of vibration-induced image blurring with the aim of determining structural parameters that are the input data for calculating the vector components of the vibration movement of the studied material point. The article describes and justifies the use of the new methodology of measuring the modulus and components of the vector of reciprocating vibration movement of the studied material point on the basis of the analysis of geometrical parameters of the trace of vibration-induced image blur of the round mark. The article determines the informative parameters of the geometrical structure of the vibration-induced image blur. The authors suggest and provide reasons for the use of the methodology of measuring these parameters with the following calculation of the modulus and the components of the amplitude vector of vibration movement of a studied material point.
