Holographic methods for analysis of vibrodrives

Abstract

An important feature of mechanisms containing links made from active materials (e.g.piezoceramics) is that very often various functions could be performed by the same transducer, enabling the development of methods for designing adjustable or mechanisms, so that multiple tasks can be performed by the same mechanism, including the ability to accommodate manufacturing and part-positioning errors in order to widen applicability. The paper deals with the selection of maximal physical parameters for vibrodrives, their theoretical investigation and various design solutions. This investigation deals with the consideration of methods for determination of the vibrational characteristics of vibrodrives from holographic interferograms of linked analysis of these characteristics carried out by using numerical techniques based on the theories of piezosystem vibration and holographic interferometry.
