Technologies and equipment for straightening sheets and strips of multiple reversed bending. Objective: improvement of technologies and equipment for straightening sheets and strips on the basis of calculation methods levelling processes, software development, implementing these methods, and the development of recommendations to improve the equipment levelers with a differentiated application of levelling force to the width of the strip. The purpose of research. The basis of theoretical studies was based on methods of the theory of elasticity and plasticity, including methods of numerical iterative solutions of one-dimensional terms of continuity of the geometric parameters of the elastic line sheets were cold straightening. Assessment of the reliability of the numerical one-dimensional mathematical models implemented on the basis of the finite element approach using a software package Abaqus. Formulating and solving problems by computer-aided design configuration working roller levelers produced using elements of the theory of operations. Methods of experimental studies carried out in the laboratory include physical modeling of processes related to laboratory levelers 9?100?250. Novelty. A numerical and finite element model of cold straightening sheets multiroll leveler. The dependence between the residual nonflatness and tuning parameters levelers, namely, the difference in width of the sheet overlap and the amount of overlap for machines with a differentiated application of force related to the width of the sheet. Theoretical and practical results. On the basis of the finite-element model and the theory of planned experiment designed regression model of the levelling, for use in automated control systems levelers. Experimentally confirmed the possibility of eliminating differentiated by width flatness defects when profiling is only one roller. Experimental studies have confirmed the accuracy of the theoretical results. Effectiveness of implementation: raising the reliability of simulation results 10-15(%). Scope. Rolling production, leveler, leveling of sheets and strips.
