Dynamic study of underground loading machine’s working tool crank-rocker mechanism

Article preview

The article is devoted to the dynamic study of the underground shovel’s working tool mech-anism, assembled in accordance with a crank-rocker scheme, containing curved wings, as well as to the study of the effect on uneven movement rate, produced by the working tool mechanism; pa-rameters and structural characteristics of the shovel paw design shape. On the basis of a synthesis of the loading machine’s working tool mechanisms, a kinematic scheme with a shovel paw, con-sisting of a straight operating part and a curved working tail, is offered. A dynamic model of the mechanism based on a variable weight of shovel bulk cargo and drive parameters of the working tool is developed, a motion equation is made up. Comparison between statistical indicators of effec-tive output obtained from the shovel loaders drive mechanism and the results of a separate computer simulation of the mechanisms under analysis attest to the proposed model’s performability.

The investigation of complex production of ferromanganese nodules during its movement by flexible traction elements

Article preview

The article deals with contemporary problems of the world mineral complex, reflects the main issues of relevance and prospects of integrated development  of solid mineral resources of the seabed. The composition, morphology and potential reserves of iron-manganese nodules are presented, a complex of equipment for the extraction of iron-manganese nodules and power characteristics that influence the extraction process are considered. On the basis of a mathematical model, the relationship between the force and kinematic characteristics is defined. The basic equation of motion of bottom devices is derived, concluded the possibility of solving this equation by numerical methods.
