Monitoring of the cutting device of shearing machines for sheep

The article presents monitoring of cutting machines of sheep shearing machines. In general, shearing machines have low-cutting machines, which is due to the production of the largest wool cutting. It was found that with increasing cutting speed, the force on the cut of wool decreases. The speed of submission of the machine at strippers with low qualification is 0,3–0,7 m/s; average 0,4–0,8 m/s; high 0,5–1,1 m/s. The width of the comb grip is the main constructive parameter of the shearing machine, which affects its productivity, priority is given to wide-grasping machines having a width of 76,8 mm, with which the main sheep population is processed.

THE UNIVERSAL STRUCTURE OF A DICTIONARY ARTICLE AS A STEP TOWARDS FORMALIZING THE LEXICOGRAPHICAL DESCRIPTION OF ARCHEOLOGICAL TERMINOLOGY

This article studies the formalized lexicographic description of the archaeological terminology and aims to develop its basis — the universal dictionary entry structure. The authors prove the need for the unified description of an archaeological term in dictionaries and terminological databases. The comparative analysis of the dictionary entry structures of contemporary archaeological dictionaries and term databases has shown that the unified principles for the formalized description of an archaeological object have not yet been developed. Thus, the archaeological dictionaries, as well as the term databases, do not have the unified structure of the dictionary entry. This paper describes the systematic development of the universal structure of the dictionary entry for the archaeological term. The source of the term material was the most complete contemporary terminological dictionary — “The Dictionary of Archaeological Ceramics” by Yu. G. Kokorina (2017). As a result of the logical-conceptual and definitional analysis of the archaeological term descriptions, the authors have proposed 15 linguistic and conceptual parameters: etymology, synonyms, pragmatic parameter, shape, function, constructive parameter, obligatory structural elements, metric parameter, degree of the metric parameter manifestation, proportions, quantitative parameter, cultural-geographical parameter, and construction material. The universal character of these parameters is supposed to ensure the development of the formalized dictionary entry structure of the archaeological term. The proposed all inclusive dictionary entry structure of the archaeological term can become the foundation for the formalized lexicographic description of archaeological terminology both in dictionaries and in automated databases.

Synthesis of Constructive-Functional Parameters to Improving the Dynamic Behavior of Automatic Mechanisms

Producing of mechanisms for automatic tool (ATCM), for machining centers requires higher performance, in terms of: the reduction of effective time for tool, simplification of kinematic chain, the increasing of reliability and operational safety, the reduction of weight of the entire subassembly, the increasing of positioning accuracy in handling tools. The paper presents how these desiderate can be achieved by improving the dynamic behavior. The objectives of the paper focused on the development of a methodology which allows judicious choice of functional-constructive parameter values, still from the design phase in order to achieve an optimization of the dynamic behavior of mechanisms for automatic tool change. The inclusion of dynamic model for the actuation (hydraulic) in full dynamic model has the advantage that it takes into account real parameters which are involved in the operation of these mechanisms. This paper develops a methodology that allows judicious choice of functional-constructive parameter values, still from the design stage. To obtain a version that is the closest to optimal functioning, in terms of dynamic analysis of the mechanism, the authors propose to develop a method of multi-criteria evaluation on dynamic characteristic parameters. This method ensures the choosing the closest to optimal functioning, in terms of dynamic analysis of mechanism.
