Methodical instructions contain educational and methodological material for performing laboratory work on structural analysis of mechanisms. The work is carried out on laboratory installations - models of mechanisms. Purpose of the work: visual acquaintance with the main structural components of mechanisms and their conditional image; study of the method of drawing up structural schemes of mechanisms and carrying out structural analysis . The definition of the basic concepts of the structure of mechanisms is given, the methodology of kinematic schemes of mechanisms and structural analysis is presented. The description is prepared at the department of "Transport and technological machines and equipment" and is intended for students of mechanical specialties of all forms of education
