MATHEMATICAL MODEL OF METAL CONSTRUCTION OPTIMIZATION OF DRIVE CONVEYOR WITH THE SUSPENDED BELT AND DISTRIBUTED DRIVE

Abstract

Introduction. The article is devoted to the metal construction optimization of the drive suspension conveyor with the suspended belt and distributed drive. The article also briefly reflects current directions of the research and development work of the conveyors with the suspended belt and distributed drive. Materials and methods. The main attention is concentrated on the drive suspensions of the conveyor construction, on the working capacity conditions providing sufficient traction and coupling, as well as on the disadvantages of the existing roller suspensions’ construction. The research presents the original technical solution of the roller suspension, which is equipped with the individual drive of the motor reducer and also with the pressing device of the leading roller, and the main advantages of a roller suspension are also described in the article Results. The authors develop and present a mathematical model that allows optimizing the steel construction of the most metal-elements – load-bearing section of the drive suspension according to constructional, strength and stiffness constraints. Discussion. The realization of the proposed mathematical model is considered on the basic conveyor construction’s calculations of the steel construction’s stress-strain state. It is established that the basic drive suspension has the excessive strength, weight and the exceeded geometric parameters of the rods. Сonclusion. The conclusion about the need for multicriterion optimization of the steel drives suspension’s construction is made, as well as investigations of the configuration parameters’ influence on the massdimensional characteristics are presented.
