Abstract

The purpose of work and the task of research of features of use of conveyors with a flexible traction element in modern systems of the automated metalworking are formulated. The technological scheme of the metalworking complex which carries out operations without human intervention is presented. The article presents the relevance of the use of conveyors in processes that require precise testing during artificial movement of cargo. Based on the MatLab Simulink application package, a model of an electromechanical conveyor system with a vector-controlled induction motor is obtained. The study of static and dynamic characteristics of the transport mechanism of the metalworking complex is performed. Based on the analysis of static and dynamic modes of operation of the conveyor, the diagram of loading of the mechanism is constructed; research of character of change of amplitude of the maximum error at artificial change of the static moment is carried out. It is noted that due to the sequential processing of parts on the line, their weight decreases, which reduces the maximum error in the speed of the traction element. Using the obtained results, the study of the behavior of the system for two cases, at maximum and minimum line performance, based on the obtained dependences, it was concluded that the system remains stable in the presence of high-frequency change of artificial load. In case of high productivity, the transport system works steadily, its parameters do not exceed the established requirements (the maximum dynamic error does not exceed 3 % of nominal speed of the transport mechanism) use of the conveyor with vector control in the automated metalworking line is considered expedient. The obtained results allowed recommending the use of belt conveyors with vector-controlled asynchronous electric motors for transportation of parts during the design of automated metalworking lines.
