Bezborodov S.N. The development of rational liquid-cooled rollers for sheet materials design. -Manuscript. Thesis for a Master's degree of technical sciences, by speciality 05.02.02-Machine design, Kiev State university of technologys and design industry Ukraine, Kiev, 1999. The dissertation is devoted to questions of rollers with liquid cooling design and manufacture. Such rollers are used in the processes of sheet materials manufacture and working where heat removal is necessary. The mathematical model of roller's shell deformation is developed in the dissertation. The working roller's width that ensure material working without deformations is determined. The methods of roller's shell stiffness increace are proposed. The influence of roller surface roughness on the heat removal is shoved. The main parameters of roller manufacture are determined. The optimization model of roller cost minimization is worked out. The mechanism of waves appearance in sheet materials is studied. The methods of such naves exclusion are proposed. Key words: liquid-cooled roller, sheet material, heat removal, mathematical model, stiffness.
