Information × Registration Number 0121U114371, R & D request Title Modeling and analysis of deformation processes of adhesive layers of the root part of book blocks sewn with threads Head Paliukh Oleksandr O., Доктор технічних наук Registration Date 12-12-2021 Organization National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute" popup.description1 The purpose of scientific and technical work (STC) is: - creation of methods and means of detection of factors of destruction of the root part of the book blocks sewn by threads, on the basis of the revealed influence of thickness of an adhesive layer on change of corners of a girth and tangential corners; - theoretical studies of the processes of destruction of book products on the basis of physical and mechanical properties and changes in the structure of contacting materials during operational deformation of adhesive joints; - creation of a mathematical model of control of the technological process of adhesive bonding of the root part of the book blocks sewn with threads and the formation of an adhesive elastic composite structure; - development of an algorithm for evaluating the performance of book editions in semi-rigid covers, taking into account functional structural analysis and mathematical statistics; - development of generalized schemes and classification of factors influencing the level of quality and operational properties of book editions and the draft regulatory framework for possible use in state standards. popup.nrat_date 2024-12-09 Close
